If you had checked the requirements online, they prefer a strong stem background with courses in Physics and Calculus. However, its not a disqualifier, there will be coursework Math/Phys heavy after OCS, see the attached brochure. It is usually less competitive to get selected for OCS than other designators, I ran out of luck, however, as they denied my vision waiver. For other branches, I know that for Marines and Army OCS the biggest requirement is physical fitness
3 miles in under 24 mins
120 crunches
15 pull-ups
are bare minimums
far as I have checked with their programs. You have a good OAR score, If you really really want to go for SWO then go ahead, othwerwise submit for more than one designators
