Does that math include Algebra 2 or pre-calculus? My daughter had Algebra 2 and AP Stats before IB Math. In our school, year 1 is the same for both SL and HL. Year 2 separates them.
Did you do well in MYP maths? Did your teacher recommend you take Math HL or did you decide on your own?
For a typical Economics or business major, Math AA SL should be sufficient for you to take the AP Stats and AP calc AB exams if you want credit (SL doesn’t carry credit, typically, though you’d be very well prepared for Calc 1&Stats in your 1st year of college.)
Depending on the college and its requirements, taking the Calc AB exam could fulfill the Calc requirement for social science/business/econ majors.
However for a math-heavy economics, business, or social science major (econometrics, GIS, risk management, finance…) AI HL would be the most useful pre-req and the requirement for Economics at British universities like Imperial or LSE.
