Questions with no negative marking

Saturday, May 22nd, 2010 by Prtyagi

—    Questions with no negative marking

There are two types of questions, which have no negative marking.

1. Integer type: Students have to “calculate” down to the finest value and then indicate that value in the OMR (Optical Mark Recognition) sheet. This is where the test really lives up to its definition — “objective”. But not multiple choice.

For example, if the answer to a particular problem is 112, then the students have to arrive at the correct answer. In the answer grid that contains four columns of numbers running from 0 to 9, they have to darken 0, 1, 1 and 2. The OMR reader would read the answer as 112 and only to that answer, marks would be awarded.

2. Match the following: The students are asked to match the items in the left column with those in the right column.

A seemingly simple proposition, if you were to exercise ‘fix a couple’ and ‘eliminate one possibility’ kind of techniques. However, it would not work here.

Let the left column have (A, B, C, D) and four options in the right column be (w, x, y, z).

The final marking would look something like this: A- x,y; B- x; C- w,z; D- w,y,z.

You would have to mark exactly like this in the specially designed grid in the OMR sheet to get any credit for this question. If you were to mark all others correct and then D-w,z, no marks would be awarded for this question.

If you were able to get out of the compartment mode of thinking and look for applicability of concepts across subject areas, you would do well. For example, when you look at an area in Mechanics, you should also realize that the same concept may be present in five other topics, viz., Motion in one dimension, Motion in two dimensions, Work Energy Power, Rotational Dynamics and Laws of Motion. Which means you should be able to use one concept in different areas to get these type of ‘Match the following’ questions.

Well, that is what the JEE intends to seek in young aspirants – can you ‘size up the situation’?

Questions with negative marking

—    Questions with negative marking

When there are questions with ‘negative marking’, the first thought that comes to mind is, SHOULD I TAKE A CHANCE? If you are not 100 per cent sure of the answer, then you will not consider answering it at all, lest you get negative marks. But that is exactly what you need to avoid.

Though random guessing is thoroughly discouraged, it may still be prudent to eliminate options and get to probably two likely answers so that your probability of getting it correct goes up. This is possible in all questions, which have Multiple Choices. However, if there are no such choices given (as it was the case in two sections last year), then it is better to leave such questions alone.

Different subjects, different skills – how to study Math, Physics and Chemistry

Thursday, February 11th, 2010 by admin

Mathematics

Mathematics is the study of quantity, structure, space, and change. It is a tool we use to solve real-life problems. So, proficiency in mathematics is measured by our ability to use it to solve difficult problems.

Students who are weak in mathematics, typically, study without writing and practicing with pen and paper. They may be spending a lot of time in reading, remembering or trying to understand the problems.

Mathematics requires us to practice solving problems with pen and paper. Only by attempting problems in various ways do we become proficient in applying the quickest method in the shortest time. So, students who like to study by practising with pen and paper, automatically tend to excel in mathematics.

Physics

Physics is the study of matter and its motion through space-time and all that derives from these, such as energy and force. Physics requires thorough understanding of concepts.

Proficiency in physics is measured by our ability to reconstruct or model the physical world through the various laws it follows, and predict the outcome of a given situation. Application of formula to solve problems requires modelling the problem into solvable mathematical equations. Typically, the mathematics involved in solving the problems is very simple. Most students get stuck in the modelling of the problem. They don’t know the method of applying the formula to arrive at a mathematical model to solve the equation. If one does not understand the problem and application of the formulae, no amount of practice will help. Even if one has a perfect memory of the formula and quantities involved, it would not be possible to solve the problem. Just knowing and remembering the concepts as written in the books may not be enough.

Students who are weak in Physics, do not spend time in reading and understanding the concepts. They may be spending a lot of time in reading, remembering and practicing the problems.

Physics requires reading, thinking, visualizing, integrating and understanding. Students who spend time in reading and understanding concepts, do well in physics.

Chemistry

Chemistry is the science concerned with the composition, behaviour, structure, and properties of matter, as well as the changes it undergoes during chemical reactions. It is the study of various atoms, molecules, crystals and other aggregates of matter whether in isolation or combination, which incorporates the concepts of energy and entropy.

Physical chemistry requires thorough understanding of concepts to solve problems. Inorganic chemistry requires knowledge of properties and reactions. Organic chemistry requires understanding as well as knowledge of the compounds and their reactions. All in all, we find that there is a lot more to learn in chemistry than physics and maths combined.

Students who are weak in chemistry do not read and remember. They may be spending time in trying to understand the system or practicing the problems.

Chemistry requires reading, integrating, learning and revising. Students who spend time in reading and learning naturally do well in chemistry.

Proficiency in physics is measured by our ability to reconstruct or model the physical world through the various laws it follows, and predict the outcome of a given situation.

Tips for IIT JEE Success # 5 – Create a competitive study group

Tuesday, December 22nd, 2009 by admin

Prepare a competitive study group

Your best source of cooperation is your competition. Working with a competitive study group goes a very long way in the successful preparation of IITJEE. When you decide to study in groups, you recreate a cooperative environment to multiply your knowledge exponentially. Students can learn very quickly by sharing their knowledge, skills and resources.

Group formation guidelines

  • Look for people who are experts in certain subjects and topics.
  • Seek diversity in expertise. There should be at least one expert from each subject. Within a subject, look for experts in different areas like organic chemistry, physical chemistry, calculus, co-ordinate, electricity and magnetism, thermodynamics etc.
  • This could lead to having a group that is very diverse. It is good because you may also have different learning styles represented in your group.
  • It may not be possible to find all experts from the friend circle itself.  So, it is important to seek out experts from other areas.
  • Make a study group of five to seven people (Larger groups get unwieldy. Groups with less than 5 are difficult to sustain)

How to study in groups?

  • Ask your friends for clarifications of doubts.
  • Quiz and challenge each other with questions from the IITJEE syllabus.
  • Share useful concepts and questions
  • Be very eager to help. Answer and teach whenever somebody has a problem.
  • If you have to teach a concept, you have to have complete clarity and understanding of the concept. So you are not only helping the other group members, but also you are reinforcing your own knowledge.
  • Someone should take the role of the session leader to keep the session productive.
  • Take a few minutes at the end of the session to evaluate what you’ve done.
  • Don’t meet more than once in two weeks
  • Meet at least once a month
  • Don’t meet without a clear agenda for the meeting

Tips for IIT JEE Success #4– Attending lectures and taking notes

Friday, December 18th, 2009 by admin

Attend all lectures, even if attendance is not mandatory. Using someone else’s notes can help, but it is no substitute for attending the lecture. When you hear the information, process it, and write it in your notes, you are already beginning to learn the information. Reinforcement of the information through revision of your notes completes the learning process.

A student spends about 25 hours per week, in coaching and school, attending classes of Physics, Chemistry and mathematics.

Taking Notes From Lectures

Taking notes during a lecture can be a frustrating, almost overwhelming, job.

What should your notebook look like after a lecture?

In general, it should look a little like an outline with clear main ideas and some sub-points with a moderate amount of details and examples. There should probably be some white space so that you add notes from your text or from the next day’s lecture.

  • Sit near the front and center of the class. You will have the most direct communication with your professor, and you will less likely be distracted.
  • Read the chapter from the textbook before  the lecture. It makes a tremendous difference to the understanding of the lecture. This way, a student can focus on the difficult parts of the chapter and ask questions.
  • Learn to identify main points. Professors often give cues to what’s important by repeating information, changing their voices or rate of delivery, listing items in order of importance, and, of course, by writing on the chalkboard. What key point is the professor making?
  • Maintain eye contact with the instructor. Of course you will need to look at your notebook to write your notes, but eye contact keeps you focused on the job at hand and keeps you involved in the lecture.
  • Stay active by asking questions. Active listening keeps you on your toes. Whenever you have a doubt, immediately ask for clarification. Get very specific in the question that you ask.
  • Try to anticipate what the professor is going to say. It keeps the mind involved and active  in the learning process. Your mind does have the capacity to listen, think, write and ponder at the same time, but it does take practice. You can think faster than the lecturer can talk.
  • If the classroom is too hot or too cold, wear appropriate clothes to deal with it.

An essential skill for good note taking is good listening.

Hearing vs. Listening
Is there a difference between hearing and listening?

Yes, there is! Hearing is simply the act of perceiving sound by the ear. If you are not hearing-impaired, hearing simply happens.

Listening, however, is something you consciously choose to do. Listening requires concentration so that your brain processes meaning from words and sentences. Listening leads to learning. Most people tend to be “hard of listening” rather than “hard of hearing.”

Which is the best course material for IIT JEE?

Friday, December 18th, 2009 by admin

Most people seem to be asking this question all the time.

* “Which is a better course material – Brilliants or FIITJEE, Vidya mandir or Bansal Kota?”
* “How should I choose the best correspondence / postal course?”

It is not fair to endorse one brand over the other, particularly when I know that most of the above stated brands were rendered completely useless, less than 3 years ago, when the IIT JEE pattern was changed. The changes were made completely with the objective of reducing the impact of coaching.

The old IIT JEE coaching brands have no experience in Objective type problem solving techniques.

In this context one can understand that emerging brands in IIT JEE coaching, have better material than most old ones. In fact, buying course material from old brands is a recipe for disaster.

How does one choose the course material?

We have listed down some of the critical parameters that should be seen by the students and parents while choosing the course material

* Authors?
Ideally, it should be written by IIT graduates (who have successfully appeared in IITJEE), who are involved in IITJEE coaching. IITians understand the psychology behind successful preparation for IITJEE. By coaching students an IITian is likely to become aware of the problems faced by students.

* Based on the ‘New IITJEE Pattern’
Established teachers in old brands are well aware of the ‘Old IITJEE Pattern. They have no clue of the nuances of the new pattern. Just changing the problems from descriptive to objective type is not enough. A good course must be good on the following parameters:

* Is it time managed?
The biggest problem faced by students is managing time. The course should have a time plan to itself. Having a course material with a lot of problems is of no use unless we know the time to be spent on it. Some course materials try to give a lot of material making it impossible to complete. The total course material should be balanced in such a manner that a student can complete it within the time available.

* Strategies on solving objective type problems
Since, most of the traditional instructors did not face any objective type problems, they dont know the methods of attempting objective type problems. A lot of problems can be solved by elimination of wrong alternatives, intelligent guessing, modulating the speed, speed reading etc. The course should have special focus on the above.

* Synchronization with the school syllabus
Since most students now have to prepare along with Class XI – XII, the problem of managing IIT JEE preparation along with school studies has become more acute. The course should be such that it benefits students in synchronized study.

Other key parameters to assess the course material are:
* Online testing
BITSAT has become online. CAT has become online. It is very likely that IIT JEE also become online by 2011. Online testing also gives a good comparative assessment immediately. Students dont need to join all India test series on paper.

* Preferably in workbook format
Students should get used to solving problems in lesser space. A course material in workbook format limits the space available, forcing students to get used to the format.

Quest course for IITJEE that fits all the above requirements and more.

Tips for IIT JEE Success #3 – Develop a System- The Ultimate Weapon

Monday, December 14th, 2009 by admin

Develop a System- The Ultimate Weapon to Win the IIT JEE Battle

Compile the study material

Some questions that come to our mind are:

  • How much material?
  • What IIT JEE courses material should I use?
  • Should I study from the school textbook or the one recommended by the tuition teacher?

There is little time to complete one set of textbooks. It is next to impossible to complete two different sets. Keep just one set of text books for studying the theory (concepts, definitions) and basic problems.

The new pattern of IITJEE has brought it much closer to the school syllabus. So, ideally, it should be the textbook recommended as part of your school syllabus. There is very little difference in the theory presented from one textbook to another. After one set of textbooks is completed, students can look at other books as reference.

Similarly, keep just one set of IITJEE course material.

Note: Collecting too much material is a recipe for disaster

After you have chosen the material that is best for you, how do you put it to the best use? There are as many different ways to study, as there are different people. The trick is to find the study style that works best for you.

Read

This is one of the most useful activity. It takes minimum effort and brings maximum result. Students, who are used to studying from coaching notes, tend to avoid reading. This is the single biggest reason for their failure. No coaching notes can replace reading of textbooks.  The information you gain from reading is important. If you just “do it” without learning something, it is a waste of time. Train your mind to learn!

Read the following:

1. Title
2. Core text and examples
3. Introduction and Summary
4. Heading and subheading
5. Graphics – charts, maps, diagrams, etc. are there to make a point – don’t miss them.
6. Reading aids – italics, bold face print, chapter objective, end-of -chapter questions

Understand

You must understand thoroughly the major ideas and concepts presented. Without such a conceptual framework, you will find yourself faced with the impossible task of trying to cram hundreds of isolated facts into your memory.

* Locate and note down the new terms, which are introduced in the chapter.
* Note down statements, definitions, formulas, etc. which you must remember completely and precisely.
* If you are not able to figure out the meaning, then look it up in the glossary or dictionary.
* Study charts and figures. They usually summarize in graphic form the major ideas and facts of the chapter.

Note: It is a good idea to keep a glossary of your own in the front page of the book. Record the terms and their definition or the page number where the definition is located. This is an excellent aid to refer to when you are reviewing for an examination, as it provides a convenient outline of the course.

Ask question
Ask questions and keep trying to answer them as you read the chapters. The more the questions, the better your comprehension is likely to be. You may always add further questions as you proceed. When your mind is actively searching for answers to questions it becomes engaged in learning.

* Write down the key takeaways (learning) from every topic (make notes)
* Write down the questions that you cannot answer?
* Mark sections for clarification wherever necessary
* Review the key takeaways (notes) after completion

IIT JEE Study Planner: Minimum recommended time for self study

Tuesday, November 17th, 2009 by admin

Most students find it difficult to determine exactly how much time, they should spend in activities in studying. This is particularly important right at the beginning of the study so as to make an effective study plan.

This is complicated even more by the fact that every chapter requires different amount of time. Even different subjects require different amounts of time in theory and problems.

The different questions that come to the mind of the student are:

  • How much time should be spent in reading from the textbook?
  • Are the notes from tuition/coaching enough? Can I manage without reading the textbook?
  • Is there anything to read from the textbook in Mathematics?
  • How much time should I spend in solved examples given in the IITJEE course material>
  • How much time should be allocated to a certain topic?
  • How much time should be spent on a problem that is not getting solved before looking at the solution or asking for help?
  • How much time should I spend in testing at home?
  • How should I calculate the total time required?

We have tried to answer these questions by giving an indicative time plan.

In order to get a good rank in IITJEE, you should target a score of 5 in every topic.

You may notice that the topics where you have scored 3 or less are the ones where you have not completed the activities as per the plan.

Prepare a new plan to study the topics, where you have scored 3 or less. Identify sub-topics, concepts which are causing problems.
