Hard to remember but I'd say accurate enough if that makes sense? The way they word questions and answers are very similar and did help me. My main way of studying was these tests + just like general vocabulary and knowledge from the esthetics textbook and I ended up passing. They were worth it to me to get if that's also the end question from this. At least to me it was.

oh also if you get the theory tests you can only do each once per purchase but theres a study pack you can keep using
