DS applied for NROTC scholarship while still a senior in hs (graduated in June 2013). GPA 4.40 - all AP classes. SAT 670 math. Graduated with several academic awards. He was contacted by NROTC to ask if he would consider a Tier 2, vice Tier 3 major. He said no, he was not given a scholarship. He reapplied, choose a Tier 2 major. Just received the scholarship for Fall 2014. Here's the problem, he took calculus 2 his first semester (fall) of college and is surely getting a D. He had last had APcalculus (grade B) his junior year in hs, so it had been 16 months of no math. He also drew the short stick and was stuck with a crazy hard professor - by the professors own admission. Anyway, he just received word he got the scholarship. Does this D end it for him? Anyone know if there is any chance NROTC will allow him to retake the class? How to proceed?
