Hello there!

Greetings!

It totally depends upon the college or school in which you want to take admission , also there are many reputed schools which also conduct entrance exam for providing admission in class 11 like DPS bokaro, chinmaya bokaro etc . But generally admission is provided on the basis of your percentage in your class 10th so if you want to get a seat in a good College / school then try to get at around 85 % marks  at least.  If you are interested in knowing marks required for admission in a particular institution then do let me know so that I can help you with relevant and detailed informations.

Thankyou
