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

Monday, December 20th, 2010 by admin

Math

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

Students who are weak in math, 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 modeling the problem into solvable mathematical equations. Typically, the mathematics involved in solving the problems is very simple. Most students get stuck in the modeling 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, behavior, 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.


3 key skills – Remembering, Understanding and Practice

Monday, December 20th, 2010 by admin

We have different styles of study. Some like to read and remember, some others like to read and understand the phenomenon and still others like to practice by writing and solving.  If we want to do well in IIT JEE, we should have skills in all three areas:

  • Reading and remembering
  • Conceptual understanding
  • Practice

Every subject requires all three skills.

Reading and memorizing

Whatever we read gets retained in the head as memory. We can recall from our memory when we are needed to do so. It has been observed that we tend to remember better if we have written something ourselves. We are required to reproduce these things at will while solving problems.

We have to learn the formulae. One can understand their source by going through the derivations, wherever possible. However, eventually, what matters is that we know the formula. We can learn/remember all formulae by reading, writing, and revising them again and again. It helps to have a compendium of all formulae.

For example, if we don’t understand the derivation of formulae in mathematics, we won’t be able to apply formulae effectively. However, while solving problems, one does not have the luxury of time to derive it. So, it must be pulled out of our memory instantaneously.

Conceptual understanding

It is critical to understand the conceptual framework of a subject. It is important to understand the flow of the logic in the argument being put by the narrator. The examples and illustrations used should fit well into our understanding. We observe various phenomena around us in everyday life. Physics and chemistry attempt to explain the reason behind these phenomena through various concepts, laws, deductions etc. We should gain a thorough understanding of the system / concept being explained, before attempting to learn any formulae or solve any problems. This can be done, with the help of examples. Apply the concept to different real life situations and predict the outcome. If the understanding is correct, the outcomes predicted will be right. Conceptual, theoretical questions are a great way to check ones learning of concepts.

Practice

After writing down the formulae required and applying the concepts, we still have to solve the mathematical equations. Solving problems is a skill. If there is no limit to the time available, a lot of students may end up solving all the problems in a test. However, the key is to solve maximum number of problems in a given amount of time, which is the duration of the test. The best performer manages to solve maximum number of problems in the given time. This needs practice. In a competition, we don’t want to lose time in experimenting, deriving etc. If we have practiced enough, we would know the exact manner in which a problem can be solved. This saves time in solving a problem and gives s extra time to solve others. Therefore, to score high in a competition, practice is a must.


Which is the best course material for IIT JEE?

Saturday, December 18th, 2010 by admin

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

* “Which is a better course material – FIITJEE, VMC, BT 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.

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.

The actual time spent by the student can vary by 10% – 15% depending on the student’s personal style of study. Please consider that the time given here is the minimum that a student needs to spend. The total time spent in studying for IITJEE across 2 years should not be less than 10% of the given.


IIT JEE study Planner: Daily timetable

Monday, November 16th, 2009 by admin

All of us know how to prepare a daily timetable.

It is an essential tool is setting up a daily routine.

However, most of us have stopped using this powerful tool.

The biggest reason that students state for stopping the use of timetables is that its ineffective.

“It does not work”

“We cant follow the timetable. It makes us feel bad”

“I do better without a timetable”

“It creates pressure”

These are all valid reasons.

However, we face these problems because of the manner in which we use the timetable.

We have a habit of focusing on the failures. If we have been able to follow the timetable 80% of the time, we look at the 20% when we could not follow and declare it a failure.

In reality the 80% time that was effectively utilized made it a success. It is never possible to follow the timetable 100%. Timetable is just a tool to guide us in utilizing our time. It reminds us to start work when we want to. If the timetable is unsuitable, we should change it to suit our schedule.

However, this tool can only work if we look at its success in stead of the failure.

We feel bad only when we look at the failures.

It is the nature of the human psyche to expand whatever it focuses on. If we focus too much on the failure then we will only find failure.

In reality, failure does not exist. It is just another attempt to success. The attempt transforms into failure when we stop attempting.

In reality, we work on some kind of a timetable even without writing it. This timetable is etched in our heads. Since it is not written, there is no measurement possible.

When we write down the timetable, it will allow us exact measurement of the utilization of our time. You can hope to increase your performance only if you have a way to measure it. Without measurement, any change is performance is a mere perception. I tmay or may not reflect reality.

Please utilize the format below to plan your days.

Fill up the timetable with activities. A sample of these activities is

Wake up / Off to sleep – These times should be closest to our biological clock for maximum efficiency. The human body is designed to operate efficiently in the day time. Try to sleep by 12 midnight (latest).

School, Tuition/Coaching, Travel time

Brush, bath, toilet, Breakfast, Lunch, Dinner

Spend at least 7 hours in sleep every day

Take out a minimum of 45 minutes in physical activities like Sports, yoga, exercise everyday. You can club this activity with friends. SMS, talking with friends on cellphone etc shoul dbe limited to 30 minutes per day.

Do not spend more than 45 minutes in TV, internet, video games etc.

IIT JEE study Planner: Weekly timetable

Monday, November 16th, 2009 by admin

Students have a different schedule for every day of the week.

It is advisable to put together a weekly timetable.

This will give us a good view of the time available  in a week.

There are some weekdays when students have to attend both school and IIT JEE coaching / Tuition. This leaves very little time for self study.

There are days when we have the entire afternoon, after school, available for self study.

The weekdays are of particular importance. This is the only time, when students get a lot of time to cover all the pending work.

Unlike Class X, when students take it easy on weekends, IIT JEE preparation calls for extra studies on weekends.

Weekly planner

Sunday
Monday
Tuesday
Wednesday
Thursday
Friday
Saturday

After filling in the time table, calculate the number of hours of self study, available per week. This should not be less than 30 hours. If you can study 30 hours per week regularly for 2 years, it is good.


IIT JEE Study Planner: Annual

Note down important dates: School Exams, Board Exams,  IIT JEE ((2nd Sunday of April), AIEEE (4th Sunday of April) & other competitive exams like BIT-SAT and State level entrances

Year Planner

In an year, students have about 75 days of holidays (including summer vacations, winter vacations and other holidays). This excludes the preparatory leave given before the annual exams.

On average, a student has to spend about 7-8 hours in school including travel time(35 weeks).

6 day school – 35 Sundays off and 210 days in school

5 day school – 70 days (Sat/ Sun) off and 175 days in school.

Students spend 175 to 210 days in school. this leaves 110 to 145 full days available for self study.

Mostly, ‘5 day’ schools spend an hour extra everyday as compared to ‘6 day’ schools, eventually balancing it out.

As you can see, there is enough time available at home to study for IIT JEE.

However, students tend to take the 1st 4 months, after Class X, very easy. They lose out on the time available in Summer vacation of Class XI.

The schools also take it easy. They start picking up momentum after 15 July, which is too late. By this time, the half yearly exams are just around the corner. The results are bad and the panic sets in. This is the time where most students lose confidence.

If a student is serious about cracking IITJEE, it is important that he prepares an annual plan right in the beginning of Class XI in April. This will give him a headstart over everyone else.

Almost 50% of the available free time is lost if we dont utilize the summer vacations for coverage of course.


Tips from IIT Toppers

Wednesday, September 2nd, 2009 by admin

Achin Bansal (IITJEE 2007 topper)
Work very hard. There is no substitute for hardwork. When you inch close to the exam remain relaxed. Stress can sometimes hamper results. Work Hard and leave the rest to god

Shailedra Thakur (IITJEE 1995)
My advice to students is that never lose the battle of the mind.

Srikanth Jagabathula (IIT Bombay gold medalist)
Don’t get bogged down by pressure, work is duty. You have to really slog it out to get through the test. You should be motivated throughout and Never ever in you dreams give up.


5 things to do before an exam

Tuesday, September 1st, 2009 by admin

Things to keep in mind one day before the examination:

  1. Sleep Well: You need at least 6-8 hours of sleep before the examination to keep yourself fresh while solving questions.
  2. Eat Light: Eat a light meal so that you do not feel drowsy or lethargic during the paper. But don’t go empty stomach either.
  3. Revise Wise: Revise only those topics that you have studied earlier. Do not start reading any new topics just before the examination, since this will be a waste of time and you may lose the information you have already grasped.
  4. Reach Early: You should reach the test center at least half an hour before the exam and if you haven’t seen the center before, then you must go and visit the center on the day before the exam.
    Note:
    If your examination center is in another city-

    • Reach the city positively on the day before the exam.
    • Ensure the place of your stay there is calm, clean and conducive to study.
    • In actuality it does not make any difference whether the center is in your city or in some other city. So get the fear of an unknown city out of your mind.
  5. Right Stuff: Keep a wristwatch, your permission letter, a pen, two pencils (sharpened at both ends), an eraser, a sharpener and other relevant stationary systematically with you.
