Which Question of same Concept have been repeated In JEE Main and JEE Advance Consecutive in last 5-6 years Analysis

Very rare case.

But to give you an idea during jee advance 2015 some questions were repeated from 19th century IIT jee papers.

Still without involving in this, you should focus to strengthen your concepts so as to score Good in jee exams.

All the best!!!

One important think to note is that questions in both exams rarely or don't at all repeat but however concepts might repeat. Do solve books like Practice Sets by Arihant to get an idea of concepts stressed in both exams and also solve previous papers.

Hello Ashitosh,

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.
