This app is pretty useful for med students, it has lots of infos about real cases . Also is easy to use due to its simple and nice user interface

too much money i wantlolsssss ,

No no no

I couldn’t even have it for an hour. I wanted the cases because I want to study for a test in healthcare. But no. You have to buy all the others and all you get to play is cardiology. That’s all. I deleted it in a heartbeat. I don’t like to pay for money eaters, and I am not going to start now. If you guys want to respond, do it. But until you change it, nobody will play your games. Only money wasters or rich people 🤑😡😡😡 Update: ;-; good response

Developer Response ,

We are sorry you are upset by the price. It is set by the content owner, McGraw-Hill, who employs teams of doctors and medical experts to assure that the medical information in this app is accurate and up to date. Any errors could lead to harm for patients so the utmost care and attention to detail is used when developing medical content. It's taken years of work by highly trained medical experts to assemble the content for this application. Also, the price is the same as the physical book to be fair to all users of this content.

well organized, directly applicable to exam - cases are nearly identical to the practice cases, covers everything you need to know for step 2 CS
