Hey there,
I know I'm not Neil but we have exchanged messages many times. Anyway, I will be taking the entrance exam in about a month and given that I pass, I have already made the decision to go there. It would be great if you go too! We can be two Americans on a journey together...hehe.
About applying and sample questions and such. I've listed a link below with the sample questions for the test. You're best bet is to call Viera, an administration lady in New York, and ask her for the information packet. I got one in the mail yesterday and it also had more sample questions (than the website) and such; along with a study guide. Viera told me that they've denied students with Chemistry degrees because they didn't do well on the test. I don't know if this is for sure but I do know that the entrance exam is the most important part. It proves you know the basics. Grades can help but if you got an "A" in a subject and then forgot it all, you're useless in that subject. If another student got a "B" and remembered enough for the exam, he is much better off than student 1.
As far as your MCAT's go, Neil is the best one for this question but from what I've read in the information packet, they're not recognized. In a way this is a disadvantage to you but also it shows the structure behind the school; they're proud of the way they do things and also it's Czech law to take their entrance exam, or in any other medical school in CR. It's no big deal if you just study, that's my guess. 30 questions in three fields (bio, chem, phys) and you can just find a proctoring service anywhere around where you live. The usual cost is about $15/test or even per hour. I've enclosed a PDF file with proctoring services in each state.
