Yes, you can enlist in the Reserve but you to have pass th physical, basic training, Advance individual training. Some of these trainings will last over 5 months. While in the Reserve you can go to school depending on your contract, you have to finish your contract in the Reserve whenever how long that will be ..after obtaining your degree, you can go active duty but the needs of the army..they can send you anywhere like Anchorage Alaska, the needs of the Army. But you can put a wish list where you want to be statinoned, that sometimes works but rarely. Since you have a degree you can be automatically promoted to E-4 and chances of SGT is even better..But remember always have paperwork of recruiter promised you. He can promise you Hawaii or high speed schools unless you see orders, its not true. Always keep and have paperwork of what is promised to you. Changing your MOS you have to go to another school its best to go MOS schools during your time in the Reserve because active duty schools is very competitive.
