Exam

I'm going to Blagoevgrad for an exam. It's one of the two exams left until I finish my bachelor's degree on Physics in the South-West University in the town. The exam is on "Differential equations" and it's left from the second year in the university. The other exam I have to pass is "Theoretical Physics part 4", led by the same teacher, M. Tassev.
Wish me luck :)
When I get back I'll test some more caching engines and will post here the step-by-step result.
