Hi,

Improvement examination is conducted by CBSE to give a chance to students who are not satisfied or failed in any subject in class 12th. The terms of the exams are as:

• Only CBSE students are allowed for its improvement examination
• Candidate must fill improvement examination in consecutive year after their class 12th.

First of chose your subjects in which you need to improve. Then fill the form of Improvement examination with the subjects and applicable fees. Note that:

• Practical marks will be carried out from your original result, and you do not need to appear for it again.
• For the subjects you do not chose, the previous marks will be considered.
• For the subjects you are appearing in re-examination, the best of two marks will be considered. Means, if one get less marks in improvement examination, then previous attempt marks will be considered.

I hope it covers your doubt.

Thank you!
