They cover a range of subjects (ones that are often the most difficult for students and therefore require a lot of explanation) and the format is great - exactly the way studying should work!

As advertised, the best way to study when you've procrastinated and need to learn it all for the exam (and it does all the stats of what's most common for you)!
