Wow that's quite a story. I don't exactly know how the british system works, but most of my friends tell me that the entrance acc. to them is based on the Standard A levels. In fact, almost all my british friends only did A1 (or something like that). It's very basic chem., bio., and phys. (or math). If you take math for an option, it's a joke coz it's just a bunch of algebra, algebra 2 (american standard) and a bit of geometry, sequences, and probability here and there.

Anyway the best advice I can give you is to take the entrance exam as soon as possible as you have a much better chance of getting through. And applying through an agency is another advantage (although it is quite expensive and not the best alternative). The reason I didn't choose Hungary and Poland for my medical education is mainly due to the language. Learning those languages is actually quite worse (as Polish is one of the hardest European languages and Hungarian...well it's just limited to that one country and isn't related to any other except probably to turkish and finnish).

Emphasis on language shouldn't be a top priority in med school (although there are many who can balance out both) as med school is quite intensive (i'm sure you know that already). So I was pretty much left out with the CR and Slovakia and the CR has a much better economic standing and a world-wide reputation for their high academic standards.

Good luck (hodně štěstí)with your choice!
