Yes for business, no for eco but the checkpoints for eco is sorta similar and okayish but it only has detailed answers for 2-3 years including essaysdo they have these types of books for economics, business, sor1, legal..
^ I agree with this. Coroneos (the yellow book) actually has answers that are much more detailed and more comprehensive overall. I suggest, for maths, if you know any past students who are selling the 2014 edition for cheap, then just buy it. You really don't need the 2015 edition because to be honest, when it first comes out, the prices are really expensive and you're really only getting one extra paper and set of answers (which, I'm sure your teacher can provide for you anyway)I would actually avoid using Success One. I know at least for Chemistry, there are times when the answers are not what the markers wanted, and it actually gets it wrong.
I prefer these ones:
