Thanks! :] BTW i've been doing TBR Biol because I was doing pretty well in the EK 1001 for bio. However, I feel that TBR biol is so difficult. I'm not sure if it's helping or not because i'm only getting like 1/5 correct. It'll have some weird explanation which makes sense, but it's like I don't know why I would have thought of this mathematical approach to this.
I read in the 30+ forum that a lot of people used EK 1001 for biol, but I'm trying to get into 11/12 so should I keep doing TBR or go back to EK?
