Revision of Class 11 Parallel to Class 12 for JEE

People have a tendency of forgetting things that they don't see often, and this is why revision is important. Same is the case with JEE preparation, which is divided into 2 parts - class 11 and class 12. If you don't revise the syllabus of class 11 while studying the new topics of class 12, you are most likely to forget them, or at least, a part of them. However, if you revise them from time to time, they will remain fresh in your memory.

Have you noticed that inorganic chemistry is difficult to remember and it is very likely to forget it if you don't revise it often? Whereas, formulas of calculus are difficult to memorize in the beginning, but soon they are embedded into your memory and you can even recall them in your sleep? This is because, with calculus, you practice a lot of questions. This is generally not the case with inorganic chemistry. Many students study an inorganic chemistry chapter and then don't practice many problems of the same and leave that chapter aside. Also, many chapters of inorganic chemistry are not encountered while studying other topics. This is a major reason that many students find it hard to memorize. However, if timely revision is done, things will be intact in the memory.

Effective Revision Tips

Let's discuss some effective revision techniques that would help you in remembering all that you study.

Take Notes

Many students have a habit of marking everything in the textbook itself. While it's good to highlight important points in the book, making notes would make your revision much easier. In your notes, you can write things as per your understanding, and also include the various tips and tricks that you find useful. Your notes can also include some important questions and their explanations, that you think are good to revise just before the exam day.

If you make your own handwritten notes, you will not have to turn the pages of the textbook just before your exam day; just read the notes and be done.

Make Memory Maps

Memory maps, in context of making notes, are basically a pictorial or chart representation of concepts. Pictures and flow charts are easy to memorize. Hence, if you can pen down a concept as a memory map, it will be easy to remember, as well as will enhance your understanding of the topic.

Don't make complex memory maps - make them such that they are easy to remember and revise. You should create memory maps in a way that the revision happens really quickly, focusing only on the key concepts as well as the concepts/formulae that you happen to forget.

Important topics to revise

The following are some of the most important topics that you should definitely consider revising. These are all from class 11th syllabus:


Physics is one such subject where the class 11th syllabus is extremely important. Some of the important topics in 11th class in JEE Physics that you should revise are:

  • Newton's Laws of motion: keep solving problems of this chapter so as to stay in touch. It is important because you would anyway be writing force/acceleration equations in chapters in class 12th when you study about coulombic force among charges.
  • Law of Conservation of Momentum: just like Newton's Laws of motion, this chapter is extremely important. It carries significant weightage in JEE. Moreover, a lot of problems of electromagnetism involve the application of this law. Basically, in JEE, many problems are a combination of class 12th and class 11th concepts. For instance, Newton's Law or Law of conservation of momentum applied to charged objects. You cannot afford to lose marks in such problems because they may be seemingly complicated, but they are actually quite easy to crack if you know the concepts well.
  • Law of Conservation of Energy: this is again extremely important because the electrostatic force of attraction is a conservative force and so, just like from the chapters above, there are often combination questions in JEE which involve a combination of electrostatic force of attraction and law of conservation of energy.


In Chemistry, there are 2 really important chapters from class 11th that you should definitely be strong at:

  • Mole Concept: you will be applying mole concept in various problems throughout your JEE preparation. You should, therefore, make sure to not lose touch with this chapter. There are so many problems from inorganic and organic chemistry that can only be solved if you have a firm command over mole concept. Make sure to solve ample of problems from this chapter.
  • Periodic Table: periodic table and the associated trends form the backbone of modern inorganic chemistry. You should, therefore, be absolutely comfortable with this chapter in order to do well in JEE chemistry.


In maths some of the key chapters from class 11th syllabus include:

  • Complex numbers: this chapter is slightly tricky. However, it is extremely useful to crack tough problems of coordinate geometry. For instance, a seemingly difficult problem of coordinate geometry may involve application of rotation logic from complex numbers. It is also one of the chapters that have a decent weightage in JEE syllabus. Therefore, you should make sure to revise it regularly and be a master at it.
  • Permutations and Combinations: this is also one of the difficult chapters in JEE syllabus. However, it is important because a lot of problems from probability chapter involve direct application of permutations and combinations. You may miss out on an easy problem on probability just because you were not that comfortable with this chapter. Make sure to revise the key formulae from this chapter regularly.

Managing revision of class 11 along with class 12

Students often face a challenge in balancing between learning new concepts and revising the existing concepts learnt. Here are 3 excellent points that you should keep in mind to master the art of revising class 11th syllabus parallel to class 12th:

  • Set aside time for revision on a daily basis: the best way to make sure that you revise regularly is to discipline yourself in such a way that you spend at least an hour worth of time on a daily basis in revising the concepts of class 11th. This discipline will go a long way with you in life.
  • Make short notes: you should create 1 page summary for each chapter in the JEE syllabus. You can then either maintain it as a physical folder or maybe a digital copy in your smartphone. This copy can be used to revise the syllabus during "filler" time. Filler time is a free time like the time during travel/commute, etc. You can quickly brush-up your short notes during this free time.
  • Solve problems: you should purchase a revision package that contains only and only practice problems. You should then solve this revision package throughout class 12th, primarily covering the class 11th portion. This way, you will get an archive of challenging problems which will help you develop your problem-solving skills and at the same time simplify the revision process for you.
