I'm a 92F SGT, I'm taking college courses. How else can I gain more promotion points?

Correspondence courses are often untapped sources for points.

Increase PT, weapons qual score, volunteer and earn the MOVSM (I worked at our Division museum in the archives during four day weekends and racked up the hours quick), make sure your ERB is accurate and that you've received awards you're eligible for (ie driver's badge), college, earn ACH in NCOES, try to walk on at Air Assault or go to any school you can get (UPL, EPO, etc.).

Army Ed is gonna be your savior. Hazmat 62, combatives, Unit Armorer Course, anything you can get your schools ncoic or oic to send you too, and Awards.
