Hello,
I hope you are doing well, If you passed in your previous exam but still applied for improvement exam but somehow you dont want to appear for the exam then you will not be failed. You can use your previous marksheet that you got. If you applied for 4 subjects and want to appear for just 1-2 subject then in that case also you can do it. Your new marksheet will be delivered at your house.
I hope you find this information helpful. I wish you all the best for your future.
Good Luck
