Hahahaha, how perfectly naive, a seemingly consistent opinion
Acer are not the only ones who dissaprove, as do AMSA and every other medical school in the country. Mostly because of price. It is a ridiculous investment that often tells you to say certain things in your interview, tells you to expect certain questions. The predispose you approach the whole admission process from an ultimately biased perspective. Getting hints is fine, but the risk vs. price is absurd
I do not only discourage them from experience, but also on the principles. These are overpriced organisation who use recycled questions and spread rumours about interviews which are untrue and greatly piss off the faculties. Avoid them, and their so called experts.
