I have started revising properly, but I don't know how I am ever going to remember everything. I don't know whether anything is sinking in at all. I mean, in 2 months time, am I going to remember that iron is the catalyst in the Haber process or what denitrifying bacteria do? I am organised, have all but 1 revision guide I need, have some practice papers (limited though), and make notes and diagrams, but as nobody as helped me so far in what to expect, I just feel that I am on my own, and I am worried that I am not revising enough. I did 2+ hours yesterday, and have probably done 1.5 at least today. I just don't know how I am going to remember everything...
