Would you do Green-to-Gold or OCS?

It really just depends on what you are trying to accomplish and how much school you have left to complete. I suggest you go see you Career Counselor and have him explain the benefits of both programs. For instance I suggest the Green to Gold Active Duty Option because you keep your pay and allowances while you are going to school but you are only given 21 months to complete your degree. There is a lot of information you need in order to make the right choice for your situation. Basically its a harder question than you may think because it really is different for each persons situation.

Depends...do you already have a 4-year degree?

If not, you do not qualify for OCS.
