It can be useful to know just what the curve is on each of the Subject exams. For example, if you find yourself omitting 1 out of every 5 questions on the Physics exam, you are in actuality doing quite well. So I provide the following in the hope of being useful.
Raw to Scale Score Conversions from The Official Study Guide for All SAT Subject Tests from the College Board. These are from the actual Sept. 2005 test tables.
These will, of course, vary from test period to test period (typically +-2), but are generally good guides.
Raw Score = (#Correct Answers) - (#Incorrect Answers * .25)
