Hi guys, so I created an account just to ask this question cus I'm a bit conflicted. I don't do physics currently and I can't switch into unit 1/2 now so I want to pick it up 3/4 however, some people are telling me it's difficult whilst others are not. I do methods, chem and bio this year and I'm getting over 80s for all the SACS but I haven't done physics since yr 10 where I did pre-IGCSE mixed science in New Zealand. I need to chose my final subjects by Friday this week so I was wondering if you guys could help me out a bit. Do you think I should do it? And if I could pull it off, what areas of unit 1/2 would I need to understand. If I am gonna do it, I'm thinking of buying the 3/4 textbook and jumping straight into that in the holidays. Please help me out, my guts telling me to do it but my brain keeps changing my thoughts.
