Scoring practice tests

Here's a generic way of calculating your success on practice exams. It's not exact in all cases due to the scaling of the individual topics/exams, but often can be a great predictor of your readiness. I saw this concept on this forum some time back, but can't remember where. Anyway, it goes something like this:

Take the number of correct answers on your practice exam and multiply them by 100. Then take this number and divide it by the total number of questions. This will give you a score based on 100. We then take this score and multiply it by .6 plus 20. The result is a weighted score that compares to the CLEP scoring system. Here's an example:

You have answered 90 questions and 58 are correct. So, we take 58 and multiply by 100 which equals 5800. We then divide 5800 by 90 total questions which gives us 64.4 out of 100.

Now, we take 64.4 and multiply by .06 to get 38.64. Next, we take the 38.64 and add 20 points. This gives us a weighted score of 58.64, rounding up to 59 out of 80.

If there are only 80 questions, there is a lot less math involved...

It is believed that this scoring system (score X .06) + 20, is close to the way CLEPs are graded. I can't verify this, but it makes sense. The .06 is the value each correct answer receives and the 20 refers to the 20 unscored "experimental test" questions on each exam.

I welcome all other comments and ideas regarding these theories.
