I am on track to get a B+ by the end of the year in AP Calc AB, and as a freshman it's quite stressful. It'll be extremely hard for me to push my grade up to an A-...my parents say that I must devote all my time to calc now and get the A- because top colleges will overlook me due to this B+. I get easy As in all my other classes, but I also don't really have much else to put to the table at the moment, as a large portion of my life so far has been spent on soccer...consistent injuries mean that this might not work out for me. Is it true that my chances reduce drastically when I apply to top colleges such as MIT? Is all the extra time I might spend worth the A- which isn't even guaranteed?
