Just passed the promotion board to E-5. What correspondence courses can I do to earn points?

Don't do correspondence for points. Take useful courses to make yourself a better future NCO for your unit and your Soldiers.

When in doubt, visit your friendly neighborhood education office and ask them as they are the SMEs (or at least should be) on which courses give you points.

You can take most of them on the site from AKO, skillport. It has changed a lot but when I would do them I would get the hours the next day when I finished the whole section. There are a lot to do depending on what you want to learn or just get points for.
