What are some ways to raise promotion points (currently at 370)? Are there any worthwhile courses/videos?

The Army Pre-Commission Correspondence Course has TONS of points, garnered as you complete each subcourse. It will take a while to complete the course but you start getting points right away.

I know you don't get points for it anymore with exception to commandant list and distinguished honor grad but have you been to BLC? Also how are you looking on awards? If you are looking for ways to get one, the easiest way to start for me was boards. Also, start doing community service and logging it to go towards an MOVSM. PT/Weapons is where you can really up your points. As far as military schools, try asking if you can go airborne, air assault, SERE, CLS, Bus Driver, and MOS specialty schools. the possiblities are endless, just depends on what you want to do and what your unit allows you to attend. You can always try to enroll/request for thngs, the worst thing that can happen is to be turned down.

go to ranger school
