How can you max out on your correspondence courses? Where do I need to go to take the courses?

I recommend Army e-learning. The description of the course lets you know how many hours you receive. If minutes is listed, simply convert to hours. How to max out? Do enough to max out. Don’t take the easy way through them, go through the courses and get something out of them. Good luck.

Skillport is the option I used for correspondence courses, I believe it is around 480 hours to max out for promotion points.
