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?
This question is highly dependent on personal circumstance (which type of job you plan to pursue, other skills you have that employers might want, how competitive the job market is, which university your degree is from, etc.), but based on the information given I would say it is better to just take the D is most circumstances. The completion of a degree in itself indicates to employers that you had the tenacity to stick with a program for an extended amount of time and is overall (usually) one of the most important factors in getting a job that does not require additional schooling.
Many employers do not check transcripts and are instead looking for other skills. If your schooling has prepared you enough in other ways, one bad mark is not likely to be a make or break when it comes to job hunting. However, I think the best thing would be to consider the specific job you are hoping to get after graduation and decide from there.
