I have been preparing for JEE paper 2 since last year and now for 2 months am focusing on 12th board exam which ends on march 21.
It's good that you have started preparing for boards exams as they are near and also have good weightage in your jee ranking.
After your boards, you should go through model papers and the previous year papers. In this way you will be able to cover alot of diff topics and concepts with each paper. This would be helpful.
Thank you.
You have though correctly. But revise the concepts only which includes your notes. And you can attempt question papers daily and when you are done with your revision you can do 3 question papers a day.
All the best
