['At one point last semester, I realized I really needed a B in one my classes to get the GPA I wanted!', 'Did you get the B?', 'Yep! I knew that if I studied like I did that I could do well!']
That is great news, good job.
I really needed to get a B in calculus! I studied so hard for the final and I knew that I was gonna do well when I was walking into it.
