Hello Vaishnavi,

With regards to your previous query, for weekly mock tests of JEE you have to change your strategy little bit.

For efficient preparation, it is recommended to go with not more that 3 mock tests a week and for those 3 tests make your proper analysis of your shortcomings and also make a note of your strong areas so that you can work out your plan accordingly.

Now for week areas just solve some more question either from any of your book or you can get a lot of questions from Google but try to solve at least 10 questions of different difficulty level from your weak concepts.

You can download different previous year's question papers and sample papers of JEE-Main from the link given below :-
