Should I retake this class?

<p>I’ve been a really strong Math student. It’s my major. </p>

<p>My average GPA in Math is 3.9. The lowest I’ve received is 3.7. Well, up until now, I received a 3.1 in Linear Algebra. Why? I missed one of the exams, and prof. is a ***** and didn’t let me make it up. </p>

<p>I’m not happy. I also know that in order to receive Honors Math Degree at the end, you need to have a 3.5 or above in every class. So if I get a 3.9 the 2nd time, I will have a 3.5 average for the class.</p>

<p>Do you think I should retake this course?</p>
