Would it be better to drop a class or receive a D? I have hit a wall.  I will receive a D in a math course (my major), C- but doubtful.  D is passing according to university.  It would drop my gpa from 3.6 to 3.3. Two more courses after this to take, so a lower gpa might follow.  Does gpa matter when applying for jobs in the math/science field?  Let me say, I am not going to grad school, I am an older return student, so being a single mom, I would like to wrap this Bachelor's in Math up.  Will keeping a D negatively impact job prospects in any way, or having the degree is the only thing that matters?
Take the D and move on.  It is just one course.
