the university in prague and the one in Hradec are both Charles university.Charles univeristy has five faculties , 3 in prague, 1 in hradec and i in pilzen.i studied inCzech also but i went to Masarky university in Brno. Studying in Czech is very good but i would be honest it is very demanding.as long as u study hard then it would be fine because at times abt 50 can start in first yr and only 25 could make it to the next yr. as for my own school as long as u pass ur exams ,they would always be space for u in the next yr or class and my school does not fail student on purpose.although i heard that some faculties in prague always take a lot of student but they do not plan on passing everyone to the next yr and that is why u see a great gap btw the number of students that came in for the first yr and those that made it to the second yr. but that is wht i told,am not sure.
