So basically, as someone who loves maths and want to learn as much as possible, I should choose IB further maths HL as it's more challenging? It covers more content right?I heard CIE further maths covered contents from undergrad first and second years as well. So as an aspiring Mathematician, I definitely should go for IB Further math HL right?Why not CIE specifically? How is one specifically better than the other in terms of content and rigour?I could study go through CIE content from their books for STEP papers, no problem with that. No reason why I should go for CIE further math only because of STEP.I am more concerned about what I learn — how much I learn and to what depth. Does CIE further math cover more content or IB further math HL? What about depth? Which is better for learning?
Note. I am not familiar with STEP preparation. I will post about it later on. But as far as I know CIE does't have any book for further math. How should I prepare for STEP in case I decide to go for IB Further Math HL and self study the missing CIE further Math topics for STEP?
