This humidifier is pretty good but not as the write.  The write say that It cover a room up to 500SF.  Well my room is 400SF +/_ it dose not live up to my expectation of covering this area..

I think most of it is common sense, very simple easy to understand, it makes for a good summary review

I haven't taken the exam yet, but I am hoping that your study system will help me in my quest to achieve certification.  It looks like an extensive review that should help me to be well prepared.  The cost of your product is certainly worth the peace of mind I will have going into  going into the exam.  My old eyes would benefit from a slightly larger font, however.

So far I haven't had too much time to review it.  I am attending school.  However, from what I did review it's a great review.

It is OK, maybe it is to soon to review it, since I have only been using for a month, so far, it is doing as expected

I think this is a good product I am using it to get ready for the test I am an older adult. I just think is they had a few more videos to view for the math section would help.

Amazon is asking me to rate this copy, but I bought it because I wore out the past two.

So I'd say it's good :)
