### Guessing and eliminating answer choises

If I can eliminate one answer choice, should I guess on that problem? I was just wondering what is the best way to approach a problem when you can eliminate one answer choice. I know they subtract some percent of the questions you get wrong from your score, so how many do you have to eliminate in order to safely guess?

I wrote something about this on the following page:"As a correction for haphazard guessing, one fourth of the number of questions you answer incorrectly is subtracted from the number of questions you answer correctly." - ETS

Feel free to check my math, but if you eliminate 1, 2, or 3 of the answer choices then that statistically corresponds respectively to 1/16, 1/6, or 3/8 points added to your raw score (assuming you guess randomly from the remaining answers).
