Query: Good attempt but falls short

It's a study aid for the CCNA study guide. It lets you plan a study schedule and track the progress (big deal ) you can do that with any schedule program. It has tons of questions ( over 600 ?) some are the same as in the book and a lots of new ones. You have the usual two modes for testing, practice and timed. The practice mode does show you the correct answer but with no explanations. The timed mode gives you nothing. Only how many questions you get right. Will not show you the correct answers or even which ones you missed or answered correctly. No explanations at all. And of course my biggest objection as always with these types of test questions is the Inability to print the questions.
