Cracked the CLEP "Scoring Secret"?!!!

[Southron Boy]

I was trying to figure out how many questions I would need to get right to achieve a certain score. So far, everything I have read about the CLEP scoring method states that it is a weighted score, and that it is shrouded in mystery.

Analyze this:

FACT: The lowest possible score is a 20. The hight possible is an 80.

FACT: Approx. 1/2 the questions on the test must be successfully answered to get a 50, or a pass.


Now, the hypothesis: In a 100 question test, such as Sociology and many others, there are only 60 possible points (between 20-80) for 100 questions.

60 points divided by 100 questions = .6pts

If each questions is worth .6 points, 50 correct questions = 50q X .6pts = 30pts

You must add 20 since 0 correct questions = 20pts.

30 points + 20 points = 50 points, or a pass.

Now:

If each point in a 100 question test is worth .6 points, 100 questions X .6 points = 60; 60 + 20 = 80.

By this formula, answering 75 questions correctly would translate to a score of 65.

What do y'all think?
