The same Miles can explain the same thing three ways. Pick the one that makes it stick for you — the Teaching tone button is beside the message box.
Professor — rigorous, precise explanations with correct terminology, like a university lecturer.
Fun & Memorable — everyday analogies, concepts as characters, and a short phrase you'll still have in the exam. This is the one you start with.
Exam Coach — concise, high-yield bullets and exactly what you need for the test.
Every answer carries its tone at the top, so you always know which voice you are reading.
Changing your mind about one answer
The action bar under an answer has Regenerate as… with the same three rows. Picking one rewrites that answer in place in the new tone and leaves the rest of the conversation alone. It costs a question, the same as asking again.
Your choice is saved per exam
Set Professor on Series 7 and Fun & Memorable on Security+ and each book keeps its own. The choice follows your account rather than the device you set it on, and nothing overwrites a tone you have picked.
Nothing about the facts changes between tones. Miles is reading the same book either way. Only the way it tells you changes.
