My school did the AS Biology mocks for unit 1, as we have all finished that for a while now. I have personally kept revising it and, like in the mock, when completing past papers get 55+/60 so I'm fine with that now. Until the real paper I will just keep doing past papers and going over anything I forget, seems like the best way for me.
However, on unit 2 it feels like we're a bit behind as we're only about half way in of module 2 of unit 2, so i've read ahead and made notes. I'm only just starting past papers on unit 2 which will be useful as i'll see what sort of stuff they want and the kind of detail. Even if we're not behind, it feels quite rushed, especially compared to how we went through unit 1.
My school finished mathematics at christmas, chemistry about three weeks ago and physics will be finished during the week we're back from this half term, however with biology we still seem to have a good amount of content to get through! Just makes me a bit worried.
