I think it’s a great idea. It is an excellent option if your school offers few/no APs and you want to challenge yourself with a highly looked at course rigor. I’m taking 4 APs next year (maybe 5). However, by the time I finish senior year I’ll have 34 College Credit Hours from all of my DE classes. My parents highly recommended to me go this route. I should be graduating with my associate’s but I don’t think I can because the CC’s math class options for the degree were below the levels I had already taken. Anyways, listen to what @billcsho said to about DE classes at your HS. I took all of mine either online or at the college itself, minus 1 class that I took at school. I found out it wouldn’t transfer to many in-state private universities and out-of-state colleges. That’s the only tricky part with DE. You can’t guarantee that your classes will transfer to out-of-state schools.
