Interview with the Consul.

I'm gonna studying in Czech (ed: Do you mean the language or the country? In English we say "The Czech Republic" to refer to the Czech nation). So I have to pass the interview at the Czech embassy to get a visa. On March 4th I'll have an interview with the consul of the Czech Republic (ed: Or just say "the Czech counsul"). I'm feeling really scared. I have a mate who had an interview with the consul just yesterday. It lasted for about 2 hours! And He also had an English test there. They need no less than (ed: I would say "at least" rather than "no less than") pre-intermediate level. I am really afraid of any tests or exams. All the time I prepairing for them hardly, then pass it really bad  (Ed: "I study hard for them and then don't do well" We do not use the idiom "to pass poorly" in English.) because I always get nervous and think that I won't pass it so I just forget everything I know...  
Hope they won't ask me for a speaking test. I'll fail in it absolutely absolutely fail.

Don't be afraid! I think your competency level is quite good. You're struggling a bit with articles but that's the hardest part about learning English! I made corrections because this is a written entry, but if we were speaking together I would understand you 100%. Good luck on obtaining your visa!
