I am writing improvement for class 12. What if I gets less mark in my extra (5th) subject than previous year?

Dear

The CBSE board improvement exam provide students an opportunity to improve their marks , there will be no reduction in the marks . I f you score lower than your previous examination marks then the previous year's marks will be considered as final. If you fail in the CBSE Class 12 Improvement Exam then your result will be displayed in the Improvement Exam Marksheet as “ FAIL ” but you don't need to write the Compartment Exam for the Failed Subject. Your previous board exam marks will be still valid and it will be taken into account but you have to carry both marksheets while having any interview and admission.

Hope this helps !!
