hi there new person...
you are just one of the many to pass through the halls of sdn and ask the similar questions most young undergrads have about whether or not they should consider med because of their low grades.
i think you would glad to hear from me at least and a few others on this site that grades are but a portion of what makes you a competitive applicant. but im sure you knew that. but this is not to say grades arent important.
now i see that you have listed a B+, C+, C+, B, and a class you will retake.
well there are people on here with many more Cs than what you have right now and have still got accepted to med school. ie.. me and exmike along with many others. If you are worried about those Bs...heres some advice. dont overly stress about Bs. Many applicants get Cs so dont worry about that either. Just dont make it a habit.
now about retaking a class. Sure med schools are OK with it, the question is whether or not you are able to do well when you retake it. I hope that you do. Your gpa will not reflect the alleged F you might get in Calc because it will be replaced by your retake grade....
however on your AMCAS application they do average out both grades. So potentially an A and an F will come out to be a C. Just to give your warning ahead of how they grade things.
now the real question is if you have any clinical experience to see if a career in medicing might be to your liking. Just because you have the grades doesnt mean you have what it might take to be a physician. get some experience by doing some volunteer work or shadowing etc...
dont give up just because some Cs are unnecessarily keeping you down.
GL in your future endeavors as a premed. (aka douche bags from what i hear today)
(that was only a joke and in refernce to another thread not to you...i have learned that new people take offense to things quite easily so i need to do this disclaimer...
