How do you grade a practice test that has fewer than 100 questions? What about a test that has 75 questions? Here’s a simple way to get a grade idea on your tests.
Divide 100 by the number of questions you have. This gives you the worth of each question on your test. Than take that answer and multiply it by the number of questions you answered correctly.
For instance: My Macroeconomics practice test today had 75 questions. Divide 100 by 75 and get 1.33 (rounded). Multiply 1.33 by the 46 I answered correctly and I have 61.18. Rounded up I give myself the grade of 61.
Remember that no one knows how a CLEP exam is graded, so you are just trying to get as close as you can.
