February 17, 2026 | 10:30 AM IST | CBSE Class 10 Math Passing Marks: CBSE 10th students require at least 33% marks overall in Class 10 Mathematics (Standard or Basic) to pass the board exam. They need to pass separately in theory (80 marks) and internal assessment (20 marks). For Math, students need at least 26 marks in the 80-mark theory paper and 7 marks in the 20-mark internal (periodic tests, activities, notebook).
