Hello Bhavin,
In the 11th grade - Just keep your basics clear about subjects like Accounts,Statistics,Mathematics and Economics.
In the 12th grade-You are required to put more emphasis on certain subjects namely Accounts,Economics(Micro+Macro) and Mathematics(Calculus).If you do have time to spare ,you can go through the basics of Indian Contract Act.Lastly do not forget about the Class 12th exams and devote time accordingly.
After you are done with class 12th exams, you have 3 months before your CPT exam (give or take a week).You just need to plan a routine for those 3 months and you will get through.
You need keep working on your basics with Accounts , Quantitative Ability , Economics for now .
Hope this helped you
All the best
Thank you
