The answer here <em>could </em>be either B. or D. But B. is the most correct, given that the question is so general.
Yes it actually does because in most schools you have to have a gpa of 4.0
1, 2, & 4 are ways it benefits students. The other two choices seem to be more about study skills rather than student self reflection benefits.
My opinion is that it’s not too late because if you don’t have the time now you might have it next year plus it would help a lot with college and possibly make it easier. but it also depends how much time you want to spend doing school instead of having fun because i understand if your not enthusiastic about school but still want to do better at it.
hope this helps :) whatever choice you make is a good one
