It depends on what you want to major in for university. I'm taking studies and what's because I genuinely don't need SL for my course because why give yourself extra work for nothing, also a lot of the unis I asked (especially uk) said that they don't care what level as long as you have some sort of math. But if youre capable of doing SL then just continue because it won't hurt you
I know this is an old thread, but I am going to university next year on a full ride (plus stipend and academic enrichment money), and I took studies. If you take SL and it hurts your gpa, that can hurt college chances way more than taking studies.
I know this is super late but my best friend took math studies in diploma IB and got a huge entry scholarship in a school with a great reputation (and he’s in engineering, so the math is really important). If you don’t need the math too much, you’re better off staying in studies.
