Dear Ajay, It is not a very prudent idea to start your preparation thinking there will be repeated questions. It is because, though some questions may be repeated, it is very rare. And even then, there may be a little twist to the question which, unless you are clear with the concepts, is enough to throw one off balance. My suggestion is not fall into this trap of focusing too much on repeated; instead read the whole topic. Start with the easier topics, which generally carry more weightage.

I had also given JEE and in the beginning thought in the same way but after practicing more and more and analysing the pattern of questions every year, I hardly found repeated questions. If there were, then they weren't during consecutive years

All the best

Hope this helps

Dear Ajay,

Yes ofcourse there will be few topics which will be very important and scoring.

In mathematics matrices, differentiation and inyegration are very important.

In chemistry be prefecy with organic part which will help you a lot, also with periodoc table and properties.

Coming to physics motion problems, applications of laws,heat and energy will help you better.

Hope this helps.

Good luck.

HI!

Yes.previous Year questions are repeated in JEE mains

But of course if you go through 15 years archive of jee mains then you will find out what a great source of practice they are !

a good guess is - at least around 20 -25% questions are sure to be repeated from these archives ( including all three subjects). some questions are just copied as same.

example - problem from the topic- real gas - related to compressibility factor 'Z' has been repeated several times.
