"Start lesson" button is confusing

The “Start lesson” button is quite confusing when you start a course, for a few reasons:
1) The “Start lesson” button formatting suggests it’s the first/main thing you should do. However, this starts the test/exam questions, before you’ve read the material. So “Read theory” should actually be the main button here, as you want to do this first.
2) The term “lesson” is misleading as it starts the text/exam questions. In UK English a lesson is a “a period of learning or teaching”.
