Easy access to information online and ordering is quite simple and selected items are easily accessable. Sample pages are provide for most if not all books/items which helps decsion making when ordering and you also have a good idea of content. Constant email reminders especially about sales/specials offers which is also very useful, very much in contact with their customers. Books/materials are of great qulaity and content is right on the mark as it relates to the given curriculum. My girls sat their SATs few months ago and the material provided from Exam Ninja was so helpful, most impressive was the ability to purchase then obtain material by downloading, fantastic and so efficient espeically for someone like me that live accross the globe. I would definitely recommend Exam Ninja! I also enjoyed the freebie sent with my order before the last, I have one order pending so I hope to get another freebie :)
