Courses and Grades, common app

I study at a CBSE school and my school didn’t conduct any exams in 11th class and nor do I have any mid-term exams in 12th class. We write the board exams at the end of 12th class. so, I am really confused about what to put in the courses and grades section of common app. what do you think I should do?

Most people don’t have grades for 12th grade. You simply answer no for Q1 under 12th grade.

Very few schools ask for the courses and grades section - Stanford being a key exception. What does your transcript list for 11th grade marks?
