Oh my god, I’m actually doing one right now and have to vent about it. Wiley is a publicly listed publishing company and their mocks are written worse than providers whose first language isn’t even English. Ethics is usually the worst and I’ve noticed several questions that after reading the explanation and going back to the CFAI text I still think are just wrong. The mocks are okay value and ultimately help with review IF you run out of other material but the amount of errors, typos and poorly written questions becomes extremely distracting at a certain point.
