I noticed something called "difference equations". What are those?
I still feel like the sciences have too much content and 9 markers reliant on history lessons. The ib only restricts those to 3/4max marks and way less intensive and memorisation orientated, and their physics course seems way more engaging and immersive.A huge complaint that has been bubbling ever since the beginning was that there was too much emphasis on society/history at the expense of deeper theoretical knowledge.
