Revising from books can be really time consuming. Now I would say preparing a summary notebook is always important in order to crack any exam. As during revision reading the summary note book will help you coup up with most of the theories which can be helpful for the exam.

Now if you don't prepare any such then you can follow the formulae books or books you know which are available only for knowing formulae etc like JEE MAINS for last 40 days by Arihant etc. This books can be instrumental for revision.

Now if you don't want any of the above. Then I would suggest go though NCERT for the important points and markings as well as the problems from NCERT are the most basics. Now for Physics you can follow up important numericals from HCV/DC Pandey, For chemistry revision use of flowchart is very helpful especially for Organic Chemistry. Now you can make one flowchart or you can just get a pdf by searching online. For chemistry problem I would say go for P.Bahadur initial problems they are pretty basics. For Mathematics you can go through RD SHARMA/ Amit.M. Aggarwal books, the problems there will intensify your understanding as well as your skills.
