guessing on MC

There is no guessing "penalty" on the AP test. There is also no
guessing "reward". It is simply neutral.
To understand this imagine a 5 question test. Pure random
guessing should result in one correct answer and four incorrect (a
simple probability problem). The score would be positive one for the
correct answer and negative 1/4 for each incorrect. The net score is
zero, the same as leaving all questions blank.
I tell my students there is no point in random guessing but if
they have any reason to eliminate even one choice they should guess
one of the remaining ones.
Some students are such perfectionists they are afraid to answer
unless they are certain of a correct answer. This definitely
decreases their chances of passing. Random guessing on average will
not lower scores. Educated guessing will raise scores.
