Hey there! I'm currently a sophomore who took IB Pre-Calculus freshman year and was wondering whether to take AP Calculus AB or IB SL/HL Math. My current teacher recommended taking the IB SL Math class this coming school year, as she said it was required and would give an introductory view on both calculus and statistics. Though, my friend's teacher said that it wasn't required to take an IB Math class. Does anyone know whether it is required or not?
