I wrote about it before. The marking system in Poland is numerical.
1 - F 2 - E 3 - D 4 - C 5 - B 6 - A
PS. Normally, I give 2 points for each correct answer and an average maximum result is about 200. In the last form though, on the last test, I give 10, 20, 50, 100, 200 or more points, depending on my mood. In result, the final score is counted in thousands. The last test must be commemorated somehow.
