Once agn, things tt hav come out before may come out agn.. jus like "Define Relative Atomic Mass" which has come out for so many consecutive yrs (perhaps tt is the most basic fundamental concept to chem?).. ya.. so be careful when spotting qns.. oh n also..jus a reminder.. if u really got the time.. mayb u wan to go thro the core topics agn.. cos cambridge likes to cross link wif the core topics... like last yr paper 3 structured.. they ask abt the importance of reduced NADP in the process of photosynthesis n the role of negative feedback in homeostatis ya.. so.. :D Good Luck, ppl.. the no. of days to freedom is countable by your fingers.. the end is coming really soon..
