Failed my first math midterm of the quarter.?

I'm a freshman in my second quarter of college, math has never been my strong suit. This has made being a pre-med student increasingly difficult for me. I pulled off a C in calculus last quarter and I began this quarter promising myself that I would do better. I went into my first midterm and froze, resulting in an F on my first midterm. I'm really, really nervous and wondering if I should drop the cl, but I realize that dropping it would not do me any good, because I need to complete 2 more quarters of calculus for my major. Our grades are weighted 25% for 2 midterms, 40% for the final, and 10% for the homework (which I will probably get ~90% on). Suggestions? Should I drop the cl/make it p-no p, or should I grit my teeth and get through it? Suggestions for how to improve my grade? (I know the usual studying, etc. but my math foundation is really pathetic, so I'm a little scared to approach a tutor.)
