Hi all, I recently just finished my first quarter at a quant-heavy MPP program. I went into this program right after undergrad, and happen to not really be good at all when it comes to quantitative stuff--I'd gone into this program hoping to change that. This first quarter was tough, considering how the program requirement classes for this quarter are all quantitative, I won't make any excuses but I just didn't do well. Between a mix of probably being a little burnt-out as well as not being able to adapt as easily with the grad life (I was working multiple jobs as well), much of this quarter just did not go as I had hoped. I just got my first grade back and it's a 'C' (I absolutely hated the course, but hadn't been expecting worse than a 'B-') and now I'm quite worried (and expecting) similar B-minuses/C's in the other couple of classes as well. I'm sure this question gets asked all the time, but how bad will straight C's affect me later on? I know that if I try extremely hard in the next quarters I still probably will be able to mostly get B/B+'s with a scant sprinking of A-'s. How can I recover from this situation, both academically as well as within my narrative for when I'm looking for full-time jobs?
