Am I more stupid than 4 years ago?
As part of my new status of trainee teacher I have to relearn most of my A-level maths. Having started working through some old textbooks I discovered that some of it was harder than I remembered. How is this? I've been doing maths for the last 4 years (although nothing really related to A-level…) so it shouldn't be lack of practice. And if I was capable of learning it 4 years ago, why can't I do it now? Have I really lost that many braincells?
Hmm. There is only one conclusion which can be reached from this. Doing a maths degree has broken my brain.
