What should be the study plan?

Self commitment is more important than anything else in preparation.

School Student: A student going to the school should follow the 4/10 plan, that is self-study of at least 4 hrs. on school days and at least 10 hrs. of self-study on holidays. The amount of time for self-study excludes time spent in classroom coaching (if any). There must be a 7 day or 10 day revision plan as well.

12th Pass Student: A student not going to the school should follow the 10 hrs. plan, that is self-study of at least 10 hrs. everyday. The amount of time for self-study excludes time spent in classroom coaching (if any). There must be a 7 day or 10 day revision plan as well.
