will any one pls give a time table for preparation of jee for 75 days

Hello student you should prepare a time table on your own as per your daily schedules but you should follow few things mentioned below -
1)Daily atleast 8-10 hr Study
2) Daily/weekly target
3)weekly revision
4)solve previous year question papers
5)attempt mock test

Prefer NCERT to build your basic concept and make sure you do each and every example and exercise questions of Ncert before jumping to a reference book.

You can also subscribe to careers360 knockout package for preparing and qualifying the entrance examination, which offer you 100 percent money back guarantee if you do not qualify.
