After 10th, you can appear for improvement exams but only one time. Central Board of Secondary Education (CBSE) has reduced the number of attempts for improvement exams as well as compartment exams for both classes 10 and 12 students, with effect from this year.

The changes are:
Improvement exams for class 10 & 12 – reduced to one from five
Compartment exams for class 12 – reduced to three from five
Compartment exams for class 10 – reduced to four from five

Such steps are taken to make students more serious about academics. After Comprehensive Evaluation (CCE) system has been introduced, students have been found to take exams casually. But this system was introduced to remove the burden on students and reduce chances of repeating classes.
