Negative Positive
Title: RUBBISH!! - Will only frustrate you and muddle your mind !!
Review: If ratings could be negative I would give it a -Infinity!The GUI is slow, difficult to navigate and badly designed.I don't know if it was must my particular copy but the "explanations" function didn't work either. Therefore you can't check why you got something right or wrong.The overall bad quality makes you very unconfident about the accuracy of the answers which is bad when you are trying to clarify in your mind vital concepts!.I'ts a total rip-off. It seems to confirm what other people had told me regarding Sybex's shoddy quality control, and overall inadequate products.Like another reviewer I suggest purchusing the JQplus product. It's good and about 1/4 of the price....
