Showing 2 out of 2 Questions

How can I cancel my Improvement form of class 10th?

Tamajit Student Expert 23rd Oct, 2019

Hi Arshad,

As per CBSE guidelines, there is no mention of a methodology for cancelling your improvement examination or nullify your candidature for the improvement examination. However, what you can do is you can skip the improvement examination only if you do not want to appear for the examination.

CBSE generates two separate marksheets for improvement candidates: one during the normal attempt of the examination and the other after the improvement examination which carries the marks of the improvement examination, thus you can show the mark sheet of your first or normal attempt and that way there is no evidence to prove the fact that you applied for the improvement examination. But do keep in mind that you must have an explanation for the academic gap that you are going to have between class X and class XII as that might be asked in your future places of academic enrollment.
