i literally think we were seperated at birth, i too got a U in physics on my first sitting, i found it so interesting but i did absolutely no work for it, but this year its going pretty well, i've also realised how little you actually need to remember, it all about understanding, once you nail that it's pretty simple.
As for AHS ive binged watched the last three episodes of series one today( my excuse is i had two two hour mocks today
). I blame my girlfriend for this, she was bugging me to start watching it, i did, and now im hooked
the unis have sent nothing but give me offers and the generic emails they send out to offer holders. The only mention of me resitting was on my reference from my econ teacher, but it was in a good light, so i guess the unis took it pretty well. tbh, i dont think they really give a crap, unless its the 'prick' unis i.e. oxford, cambridge, imperial etc.
As for psychology, OMG, AS content is soooooooo boring(A2 is intresting but the amount you have to remember is astoundingly large ), i have no idea how i managed to scramble all that crap into my head. the way i did revision was to write notes, then rewrite them till i remembered it, so i think i rewrote all my notes about 4 times over my revision period. but thats me being weird, you just have to use a bunch of different techniques and see which works out for you. tbh, psychology you can BS your way through it, as long as you know the key concepts, you can almost make up the studies and as long as you link the results back into the question, no examiner will actually go out and look for that specific study; my teacher said you can use uncited research, which basically means you can make up a study in you the exam and theyll take (although i wouldnt recommend this unless you're really stuck )
economics? that was my first true love, till i dug deep and realised how boring my working life would be in comparison to doing engineering
