I would like some different voices on the training sections. ie alternate. I would also like to be tested within each module, at an earlier stage, not just at the end and for it to be slightly different with each module. As it stands, you know you will just get questions at the end. With some of the modules, you could easily do a quick test ever few pages. it just helps with concentration. A bit of student involvement along the way stops sleepiness - and for it to vary. If you are getting bored and tired, the information is not going in so some early participation along the way, pressing buttons, thinking for yourself, keeps the concentration level up. The information is fine. I just struggled to stay awake and made myself take notes.
