If I get the correct answer, the program usually awards 0 to 2 points. If I get a wrong or alternative answer I get -4 to -18 points. The scoring methods are not really balanced, are they?

Well, I tried it again. 100% result gives 2 points, whereas a task completed with a single mistake costs 4 to 8 points.
