I've seen 2 people so far who have gotten A* in biology A level and they both said that apparently you don't have to memorise all of the biology A level content to do well in it & that apparently they didn't. I even saw a tutor for bio a level say that too.
If that's the case, then how much of the content should I actually memorise? Could I just memorise off of the cgp book? Cause one of the students i mentioned earlier said she used a CGP book for bio a level but didn't specify what she did in particular.
