I’m not too sure what geoscience is, is it like earth science or..? Anyways I took chemistry online this year and I think it’s ok to say I would have rather taken it in person, just because chemistry can sometimes be confusing -at least for me, and I’m generally a smart person oof. Ik my answer may be biased because i took earth science in middle school and chemistry now (10th grade), but I would say take chemistry. If you take chemistry now then a LOT of things will make sense and if you do geoscience in 11th grade or smth it may be a lot easier to understand.
