Hello,

If you appear for improvement exam the best individual marks from the two marsheets will be considered for calculating your aggregate percentage.

For Example - You scored 74 in Maths Board Exam in your first attempt and now  you appear for Improvement Exam of Maths and score 88. Then the marks scored in your improvement exam will be considered (i.e 88 marks)

But if you scored 85 in Physics Board exam in  your first attempt and now  you appear for Improvement Exam of Physics and score 81. Then the marks scored in your first attempt exam will be considered (i.e 81 marks)

Hope this was helpful
