Genetics. The two main types of hemophilia are caused by gene mutations that affect the levels of clotting factors in the blood. Mutation of the FVIII gene leads to hemophilia A, also called classic hemophilia, while a mutations in the FIX gene leads to hemophilia B, also called Christmas disease.
SAT and ACT Requirements. Each school has different requirements for standardized testing. Most schools require the SAT or ACT, and many also require SAT subject tests. You must take either the SAT or ACT to submit an application to Harvard.
Harvard requires 2 semesters of Calculus instead of just one. Most medical schools require a completed Bachelor's degree, but not all schools do. Some schools only require completion of the pre-requisite courses, as listed previously, and at least 92 completed credits (you are a senior at that point). Overall, most US MD and DO medical schools require the 4-year degree, but most US Podiatry and Caribbean schools only require the 92 credits.
