My son is graduating from college and has been seriously looking for the last year at a career in the CG. Specifically, he is looking to apply to OCS. In some general discussions we've heard that acceptance is extremely difficult to say the least. Are there any specific things (Degrees, qualities, experience, ...) that the CG is looking for. He will be graduating with two degrees (A BS in biology and a BA in Environmental Studies). What could my son do to enhance his possibilities of acceptance?
