Are you using Skillport?https://usarmy.skillport.com/s.../usarmy/login.action
Skillport is all module based and you complete them fairly quickly. I got nearly 1,000 hours on there before they put a cap on the amount of points you can earn in Correspondence Courses.
You might not find anything related to your MOS, but there are definitely a lot of professional development courses on there that you can apply to soldiering. For example: Leadership, Team Building, Time Management, etc.
