Two habits worth building now

Check the regulator, not the brochure. Every course in this book has a body responsible for it. Those bodies publish lists of recognised colleges on their own websites. A college's own claim of recognition is not evidence; the regulator's list is.

Use official portals directly. Every entrance exam in this book has one official website, named in Look It Up. Apply there. Agents who offer to do it for you charge for something you can do yourself, and some of them are not agents at all.
