I received this grade for my math 208 course during the summer. I was wondering if it was acceptable or if there was any way to make it acceptable for the major requirements without retaking the course.

Before the midterm, I thought it was fine but now I'm not so sure whether it's acceptable or not. It's really bugging me whether I wasted time or not. Also not receiving as much money as usual so I need to get my degree as soon as possible before I run out of money.
