"Intersog’s books come with the content plus flash cards and end of the chapter tests that you can take to find out whether you have mastered what you have read. I don’t know about you, but I rather read a book elaborately once than going through it 10 times in a rapid fashion. With Intersog’s training books, you get to do just that. And if you happen to be getting ready for a test, you can always use the flash cards and the content to remind yourself of the most important issues."
