Barron’s is super hard and covers most of SL, so, the beginning of AS level math (not further math though). But yes I may be confusing extended math and additional math (extended math to me looks like Algebra2 with basic precalc). Still, Algebra 2 is like “regular” GCSE maths so you see the issue for OP, to have just “core maths” and jumping straight into HL.
I’ve definitely been leaning more toward HL, and after talking to the instructor I’ve felt a lot more confident about it. Thanks guys!
Officially enrolled in HL today. Thanks guys!
