Strategy and Tips for Preparation of Physical Chemistry for IIT-JEE
Physical chemistry plays a very vital role in the preparation of chemistry for IIT-JEE and other chemistry competitions. Being mathematical in nature, it appears to be somewhat tough to the students. However, it becomes relatively easier, if you use the RRP (Reading, Revision, and Practice) strategy for the preparation of Physical Chemistry.
The analysis of papers of previous years reveals that the following are the hot spots of Physical chemistry for the preparation of IIT-JEE-
- Criteria of Equilibrium state
- Relation between Kc and Kp and its applications

In fact, the final selection in IIT-JEE stands on the following four pillars-
(1) Teacher selection
It is the first and the most important criteria to crack IIT-JEE. A teacher of academic or below standard can never let you prepare well for IIT-JEE. So, you should select the best mentor that can prepare you well for IIT-JEE.
(2) Matter selection
For competitive preparation what is not to study is more important than what to study. You should emphasize more on important and relevant topics (hot spots) and practice more on quality study materials rather than being trapped in rubbish materials floating in the market.
Always remember, if your mentor selection is well then he would provide you the best and relevant study materials and therefore, material selection would become automatically well.
In my opinion, you should concentrate on NCERT books that are Encyclopedia of IIT-JEE and you should improve your application part by revision and solving practice papers and previous year’s papers within the prescribed time frame again and again.
(3)Time for starting preparation
When to start preparing for IIT-JEE? It is one of the most frequently asked questions by the IIT-JEE aspirants. In my opinion, you should start your preparation from class 11 and should maintain your tempo till the examinations. If you start too early then it would not be easy for you to maintain your pace for a longer time period and it would develop a frustration in you that is very dangerous for you and your preparation.
(4) Hard work
It is the fourth important pillar of your preparation to crack IIT-JEE in the First Attempt. You have selected the best mentors who are providing you the best study materials but you are not serious in your preparation but just wasting your time, then not even God can make you selected in IIT-JEE. In fact, there is no shortcut to success, except hard work. So, you should maintain consistency in your preparation. The regular study, regular revision, and solving practice problems and previous year’s papers in a specified time frame are the keys to your selection.
Important Tips for Preparation of IIT-JEE
(1) Select a good mentor of Chemistry. Several educational channels and the best mentors of Chemistry are available on YouTube for free. You may follow one of them rather than wandering here and there.
(2) Centralize your study to the NCERT books and one or two reference books of organic Chemistry. Don’t follow too many books otherwise, you would not be able to complete your syllabus. Always remember, different books differ being only nineteen or twenty in text quality, but never differ of being nineteen and twenty-five.
(3) Follow quality notes of a good mentor. Don’t run behind the brand, but run behind the concise and effective notes of your mentor.
(4) Prepare your own capsule notes for revision.
(5) Maintain consistency and regularity in your preparation.
(6) Revise the prepared topics regularly. Always remember, revision is not a waste of time but it makes you perfect. Always keep in mind that, “Revision is division” i.e. Revision improves your marks and ultimately your rank in the final selection.
(7) Solve practice problems and previous year’s papers in the specified time frame. It would help you to finish your paper timely in the final examination.
(8) Always be confident in your preparation, but never be overconfident. Always read the question carefully and then answer. You usually make mistakes in overconfidence and it has to be reduced.
