Chemistry

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.

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.

Physics

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.

Mathematics

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.

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

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


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

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.

Demystifying the IIT-JEE dilemma

For Students of class X going to XI or class XI going to XII
The students going from class X to XI have a lot of fire in them (carry over from class X board exam time), and so do their parents. Board exams have been rated so high (as a performance measure) in the minds of the students, that they put in everything they have in terms of scoring well during these exams. They are told throughout their class X that this is THE year, their ULTIMATE test of intelligence and aptitude.
The sad part is that it in reality is just a simple test of knowledge. It does not, in any way, measure the student in terms of (a). Grasping power (b). Conceptual understanding (c). Thoroughness in all the areas of a ’subject’ and definitely not (d). Intelligence.
I have got so tired of telling parents about this again and again that I really felt the need of just writing this down in a blog and post it on my website for everyone to see.
1. “My daughter has scored 93% in her board examination, then she is definitely a very intelligent girl and therefore has the aptitude for engineering and a chance to make it to IIT”
My take on such statements or thoughts is that your daughter is definitely ‘hard-working’ and ’sincere’, but is she intelligent…? I am not sure. So how can we be sure about her intelligence. Well, class XI might be the best initial measure for it. Class XI brings a whole variety of concepts, new theories, and entirely different set of fundamentals. If she is able to grasp class XI fully and with ease, then I can surely say she has the potential (just like I said, inital measure of intelligence). I know lots of students who secured 90% and above in class X and thought that . They thought the root sign simply cuts the square powers. I hope you get my message here, that concepts are a completely different ball game.
2. “My son had scored 90% in class X and is scoring above 80% in class XI. Therefore he is capable of clearing IIT also”

Once again, class X only shows hardwork and sincerity and class XI only shows potential. Now i shall point out the difference between class XI level of school and the class XI level of what comes in IITJEE.
The following are some of the questions from class XI school level

and the following is a question that came in IITJEE 2006 (based on class XI).
This one single question in IITJEE requires a mixed understanding of the all the three questions (school level) that I listed. So if the student has the capability to solve the 3 school questions, he might not necessarily have the approach or strategy in his head to mix the three things to solve this single problem. I have seen this ability in very few students. But, I am not saying that these few students were born with this ability. Definitely not. If that was the case, it would have been sheer discrimination and an incorrect way to select students (like the movie ‘gattica’, only the perfect people survive).
This skill of approach and strategy, can be BUILT in the students mind. There are strategies for that which will be listed in my other blogs.
The bottomline is… IITJEE is not a mystery.

(b). The spiritual help: This is the mother of all solutions to problems in life. Here I just tell students to ‘Stop thinking’ altogether. The very fact that the mind is the one which gives pain in your life, that makes you restless, gives anxiety in your life, makes you very happy at one time and extremely sad at some other time.

We are taught a lot of things in our school, college, work place and home. But we have never been told about the mind. What it is and how we can use it to our advantage, and when it becomes a evil. I will try to explain as clearly as I can. (Many have tried to explain this same thing and died painful deaths trying to help compulsive thinkers)

The brain has connections to the rest of the body through the spinal chord. Every part of your body is connected to your brain. So you cannot afford to mess around with your brain, can you?? If the wrong signals are sent, you do not know where those signals will eventually land up, and what they might convey to that part of your body. But what does the brain produce?? Nothing but ‘Thoughts’. Just like the bone marrows produces Red Blood Cells. Its just keeps producing thoughts. Thats its job. But now just wait a moment and analyze the difference between the bone marrow and your brain. Both were given to you as part of a self-driven programmed mechanism called ’save this guy… help him live’. The machinery of both was programmed in the DNA of every cell in your body. So thats what they keep doing.

But haven’t you ever noticed that you definitely have some ‘CONTROL’ over your thoughts. But you do not seem to have any control whatsoever on your bone marrow. That control is the ‘YOU’. You are not your hands, legs, brain, body. The ‘YOU’ is that control ’sometimes’ exercised. This control sometimes even appears in the form of ‘ATTENTION’ while reading a book, watching television, listening to someone speak. It can even be the ‘CONCENTRATION’ thats needed often while studying. You are simply this attention, this control, this knowing, this observer. Once you have got this, then only you will understand the next para.

Now that you have got your ‘ATTENTION’, whenever you have a thought like ‘I do not feel like’, or “I feel sleepy’, or ‘I am a loser’, or ‘I cannot…’, then just start to observe your thoughts. Simply observe without any prejudice or judgment. JUST WATCH your thoughts… if you do this the right way, your thoughts will not survive your attention. They will die/vanish.
