I had given class improvement exam after 12th..I did not fail but was not happy with my performance and got 81 percent in pcm..Now I'm final year electronics and electrical engineering student of Mumbai university and I'm planning for applying for ms in Canada.I never got a it and my cgpa as of now is 8.9..Im my class topper and as this branch is only in my college I'm university topper too.So will my class improvement exam cause any hindrance?my 10 th percentage is 88
