Hi, I did the oct 21st b123 test as well. I heard from my teachers that the grade boundaries are going to be quite high? Don't understand why as I completely flopped it. I always got an A* easily for my mock but for this one I'm hoping that I'll get a high A and do my best for physics and chemistry. Weren't the questions tricky and confusing, compared to the past papers that were quite straightforward?
I had no idea what to write for the 6 marker about the nitrogen cycle :/ I wrote BS about autotrophs, hetertrophs, herbivores and carnivores.
