Is there any way around having to have taken Diiferential Equations in college?? In the MSAR it says that you need Diif EQ or Integral Calculus. What exactly is Integral Calculus? If this question seems stupid then forgive me...I admit my stupidity. Because on the secondary it askes "What college level courses in Diff EQ AND Calculus will you complete before medical school?" I was wondering if anyone else is in a hole with this one? Thanks!
