You need to read the section at the top of the page on reapplying. It tells you the courses you need are Calc, Chemistry with lab, English, and History and if you can, Physics. I know at USNA the Calc you take depends are which level you are qualified to take. If you have already taken AP Calc or something equivalent, you might need to take the next course, Calc II etc. The academy admissions board will really be focused on your grades in these classes your first semester at college. Again, they prefer you attend a 4 year university as opposed to a community college, unless your budget only allows you to attend community college. Our DS attend a prep college, which the moderators don't really endorse as much. It was appropriate for our DS and he did get an appointment after reapplying. He took all the above mentioned courses and earned A's.
