CBSE Class 12-science Answered
Dear Student ,
There are many people who are very weak in Maths , there is something else they are very good at too. So firstly done be upset . But do something about it , you must.
To begin with , take help to comprehend the concepts correctly/, first taking the topics with maximum mark weightage
Having done that , do all questions from the NCERT of that topic.
If you are really very weak and not passing at this stage . Just focus fully on the NCERT . Buy a book that has previous years questions on that topic . Attempt those .
The Topper website has a lot of available material, including sample papers and their solution that you must do after you have done a topic by topic study
Good luck
