Certainly!

It is as per CBSE's discretion to increase or decrease the marks based on what the student has written in the Answer Booklet. Post revaluation, your marks can either increase or decrease and no further appeal is entertained by the CBSE. Those will be final scores.

The revaluation process takes around 15-20 days. Fee is INR 505/- per answer script.

However, It is not advisable for the candidate to apply for revaluation if he/she is not confident of their performance and take unwanted risk in their career by losing more marks.
