Please help for degree planning

In the US, there are programs (often known as dual enrollment but most states seem to have their own names) that enable high school students to take college courses for free or at a low cost. They get both high school and college credit for each course and is a great way to save time and money. Some students are able to cram an entire associates during this period but it isn't very common. I used to work at a large community college and we would maybe get 1 of these high school students a year. In the grand scheme of things for a high school student, an associates generally doesn't weigh more than your GPA, SAT/ACT score, and essays (maybe it changes if you plan to go to an in-state 4 year university?).

For biology, psychology, and chemistry, like ArshveerCheema mentioned, you could take several ACE courses but I can't recommend them at this time as they could limit your options. For example, if you later plan to go to med/PA/Optometry/Dental/ETC school, I'm not aware of one that accepts ACE credits for STEM gen eds. Most of these have to be completed in person at a regionally accredited college/University though more online courses have been accepted recently due to Covid. There are ways to get those RA credits but those have associated costs which may not be necessary depending on your future aspirations. Honestly, I think it would be more productive if you shadowed people in multiple professions or maybe volunteered at a local library/hospital/Lab.
