Primrose Kitten Papers

I've done the biology ones and they seem to be harder than the actual exams which can be quite discouraging

It's a good thing though at the same time, if you can do a harder paper than the real thing, then you'll be pretty prepared for the real exams.

Yeah, to be honest that's what I would hope for. Esp. for Stats, I can do the easy questions just fine but it's the harder ones I struggle with, I'd rather have more tricky questions to practice.

Here are some other threads about her papers though:

I'd read all responses thoroughly and then make a decision, but the more practice you do and the more exposure you have to different types of questions with varying the difficulty, the better. That being said though I personally haven't purchased her papers, so don't take my word for it, but doing more is always better, so as long as it is not financially demanding, I'd buy them.
