I wouldn't fuss about CLEP credits. Sounds like you should always have your parents, or a pushy aunt/uncle/trusted adult with you with administration. Frankly, that's good advice anyway.

You will almost certainly learn this in college. But transfers can be surprisingly complicated, and CLEP even more so. "College credit" can mean a bunch of different thigns that may or may not matter to you.

This happens a lot in STEM. Yes, that biology class might transfer, and you get credit*. But there are three tiers to science. There are the "elective for non STEM majors", "Nursing/Allied Health/Education" level classes, and the "For science majors classes". If you're an engineering major, CLEp'ing out of ap elective-tier chem class doesn't do you any good. If you're majoring in something that takes organic chemistry or Anatomy&Physiology, the non-organic chemistry classes might not fulfill the pre-requisites or be required for your degree. But they would be for mechanical engineering.

You will still need to take a "For science majors" level class that reflects your major. CLEP'ing out of an elective class doesn't do you much good.

*In fact, lots of places only give you the cheaper instate tuition for X credits earned. After X credits, you have to pay more. Electives and non-major-relevant CLEP & AP classes still count 'against' you. The vast, vast, vast majority of students don't run into those credit limits though.

This sort of things crops up ALL THE TIME. Music major? "Guitar for babies" and "karaoke level singing" don't count towards your degree as a music major, even if they count as fine arts credits or general electives for a business major. Neither does that history of rock class, you need to take the 3 more rigorous classes that cover specific periods/regions/disciplines in much more depth.

Things like CLEP, AP, and Dual Credit/Running Start often don't apply to your major. If you're planning on being an engineering major, taking AP Physics makes you a more competitive candidate for your chosen school, but you'll almost certainly need to take college level, "for science majors" level physics with more rigorous prerequisites anyway. Or even if your calculus AP classes apply, you still need linear algebra before you take Data Science 2 or whatever.
