“I think the ‘library’ is both concise (because it is easy to find things) and comprehensive.”
“I particularly like the red text summarizing the test results”
“The availability of all possible tests and diagnoses was helpful in simulating the actual environment for physicians.”
:  “The USMLE wasn’t as comprehensive as this. I really liked the interface – it was easy to use and seemed very responsive. It seemed much more real than other ‘simulated’ patient interactions I have seen.”
