I’m in the USAF overseas, attempting to become eligible for AECP. For this program, I need to have taken two science courses, each with a lab. They must be either both Calculus-based Chemistry, both Calculus-based Physics, or one of each.
The hardest part is finding a school that offers these with a lab somehow included as a web-only course.
I don’t know about an online lab (having studied chemistry in college, I don’t see any good way for an online lab to work- its a very hands-on kind of learning) but many schools will do course credit and lab credit separately. You may be able to get an online course credit and get credit for a lab course in the real world- lab would only be about 4 hours a week. If that’s just not at all a possibility, you can try and find a chemistry/physics professor who will work with you over the internet to design experiments you can do with materials on base, and either submit a letter saying you’ve fulfilled the lab part of a course or even get you credit at their college/university. Physics may be easier to do, as most intro physics labs require *at the most* basic electronic equipment, and often can be done with weights, springs, and a stopwatch.
