Mate, relax from what you've told me you have enough bio resources to keep you going a decade - finish using what you have first and then you can complain..
And how do you know its the 'best' if its not even out yet??
Think about it this way ... If you cant get it, no one else can either.. So, we're all in the same boat...
Just work on making your own summaries
I got the Unit 4 advantage series Bio and it's very good

contains important website and SACs and their summary notes are more brief than A+.
So I know Unit 3 is the same as well. I was gonna rely on that book but it's not publishing this year

Not really, I lack of some good summary book(I don't write summaries cos it's wasting time and takes ages,might just read notes and understand+apply).
I have almost finish with my Unit 3 course though so feel like starting exam paper. Not doing biozone cos it's tough

I might skim through Unit4 too cos I assume it will help
LOL yeah "SAME BOAT"
