I'm currently a junior and I am planing on applying in this upcoming cycle. The only math credits I have are from AP Calculus AB from High school. I have taken a course under the biology department that taught statistics but used biology situations. Would it be possible for me to use this "Biostats" course as another semester of math? If I do decide to take another math course can I take it senior year even though I'm going to submit my applications this summer? Thanks!
