Since you haven't mentioned the board, the minimum passing percentage required for CBSE is 33% and for ICSE minimum percentage is 35% in each subject.

Dear Aspirant

Although the basic criteria to pass class 11 in each subjects of the science stream is about to score at least 21 in all of the subjects out of 70, as per the state board marking rules. However in other boards as well in class 11 you need to score at least 30% marks in each and every subjects.

But yes for other boards the marks criteria may vary, however the pass marks will not exceed over 40% in any of the boards.

Good luck!!!

Dear Student ,

Your question depends on the passing marks criteria in your School. Generally in average cases 40-45% marks is accepted as passing marks . And according the passing rule , you need to gain min 30-35 out of 70 in 11th Science stream .

As per your profile suggests that you're an Engineering Aspirant , So , I would suggest you to prepare better for your board and clear the basic concepts in which specially you are weak .

Some other tips:

• Try to score better in Practical exams as these are the internal marks that your college can provide
• Do revision and give mock test daily
• keep consistency

Hope this helps !
