Dear aspirant
11th class is a basic foundation of further studies whether you pursue science,commerce or arts. You should do self study daily apart from tuitions. You must give atleast 6 hours to self study.
First clear your basics from NCERT and then jump to other books. NCERT should be on tips.
Give 2 hours to main subjects and 45 mins to language subjects.
Whatever you studied revise each and every topic at night and in the morning and then study new topics.

greetings,

if you are a science student, a regular study is very important because concepts studied in class 11 serve as a base for class 12.

make sure that you study 45 mins chemistry, 45 mins maths and 45 mins physics daily.

revise a single topic three times to attain perfection. regular studies and subsequent revision will help you clear entrance exams also.

if you are an arts student,you may study at the end moment and get 100% but try to revise daily.

if you are a commerce student revise practical subjects like accounts and economics daily for 45 mins each.

hope this helps.

good luck

Hello Dear
Well. It depends on your efficiency.You should study till you think you can remember the things. For an avg. Student 2-2.5hrs are good.
Best Wishes..!!
