Your code can’t handle test case (WA) when both mark and credit is a floating number. try this as input:
1
3
79.5
1.5
88

whats the problem 
The problem states what to print if you failed any courses. However, it doesn’t state that “course” needs to be pluralized (“course” if 1 fail, “courses” if > 1). Please update the problem statement.
Wrong answer on 21 test case. please help me

It seems there was a bug in Toph that was causing your submission verdict to appear as Wrong Answer. The bug has been fixed. Your actual verdict is Runtime Error. Your submission has been rejudged.
Hope that helps! Sorry for the confusion.

---------> Why 21 test Case is not passing?
@Fariha.Brotecs One issue that I can see in your code is that your second and third printfs do not have “\n” at the end. All your cases will end up appearing on the same line with no space in-between.
