Hi,
I’m planning on applying to top-tier universities (Ivies, etc.), but I do have 4 Bs on my transcript… all in math courses, which is my Achilles heel lol. I have one B second semester freshman year, two B+s in Calculus AB sophomore year, and a B+ in BC second semester junior year (managed to pull an A first semester because its material overlapped with AB).
I do have As in all my other courses and I’m planning on a Poli Sci/English major, which is completely unrelated to math… I also have redeeming AP scores (5 in Calc AB and probably for BC as well, 800 on Math II, and 800 SAT I Math portion).
The main thing I’m worried about is class rank- I go to a pretty competitive school but they rank based on the amount of As you get without taking into account course rigor. So my four Bs place me in top 10% only 
I don’t know, how much would this hurt me for admissions? There’s a definite trend but it just worries me… Any input would be appreciated!
