Which specific courses will help me with college credits and promotions points?

You should sign up for English. It's the first college course you should take. It will affect every grade you ever receive in your future college courses and it will affect your professional writing and how well people perceive you in your written communications in the future.

There is no shortcut to education. There are no military courses that will double as college courses for you, you have to take college. Taking college now will put you years ahead of your peers in every promotion you have in the future, especially in combat arms.

Take a trip to your local education center - they'll help you tighten your shot group. Good Luck
