In the first lesson on the school the teacher mentioned the fibonaci formula, and because I already had a little experience in programming I wrote a program witch outputs a given amount of numbers after the Fibonacci formula and showed it to the teacher who didn't really showed any reaction. At the end of my time in the school while the exams preparation he told us that last year one part of the exam was to program for the Fibonacci formula. At this point I realized that my little experience in programming was already to much for the class and why I did not learn any thing in 2 years.
Ps: sry for my bad English.
