The Full Form of CBCSS is‍ Choice based credit semester system.

The CBCS system follows the semester pattern where two consecutive semesters (odd & even) constitute an academic year; Grading and evaluation of students performance in each subject takes place at the end of each semester. CBCS uses a credit-based grading system and not a percentage-wise system. Though the use of credit-based grading is common among universities, the credit system specified by UGC is specified below.
