hi,

Yes, you can take an improvement exam if you’ve passed all subjects in your 12th board and want to improve your marks.

Here's what you need to know:

• CBSE & Most State Boards allow students to appear for improvement exams the next year after passing.

• You can choose to appear for one or more subjects.

• The better of the two scores (original or improvement) is usually considered.

Make sure to check the official website of your board for exact rules and deadlines.
