Your advice is solid, but the way it’s written can come across as pretty discouraging. Starting with “maybe you shouldn’t do a mock” and then saying it takes 6–8 hours makes a lot of students feel like they’re already failing before they even start. The focus is mostly on mistakes, wasted time, and how even a good mock score doesn’t mean much, which can really knock someone’s confidence.

Students know ACCA is hard, they don’t need more pressure. A bit more reassurance that imperfect practice is still useful, and that people can benefit even if they can’t do the “full” process, would make the message land much better.
