So, it may not have been very complicated, or very detailed, but I managed to cover some ground!
Most of it was just a recap of topics from GCSE and these were:
So the top two required a bit of time - just making a little flip paper to continuously recap each one. The middle few required very little time, as I understood the concept quite well during GCSE, but the last bullet point took the most time, and is leading into new territory for me. Consequently, I've saved most of that for a rainy day (probably tomorrow) when I will take the time to focus on it in more detail.
Basically, as the first 6 points have been completed, that means I have to do LOTS of practice questions to refine my understanding and get my head around the more complicated applications of each topic. When I've done this, I'll have completed, or understood, the first Section of C1 (six more to go)!
