GRADE CONVERSION

 

 

Below you will find information on how to convert your class exam scores into AP scores. You will also see how I convert those AP scores back into percentage grades. I know, it sounds confusing just keep reading.

 

First, there is a mathematical formula to convert any exam grade into an AP score. It goes like this:

Since the multiple choice section of the AP exam is worth 100

points, take the total number of questions that were on the multiple choice section of our test and divide 100 by that number. The answer (rounded to the nearest hundredth) will be x. For instance, if there were 60 test questions, divide 100 by 60 x = 1.67.

 

Next, note the number recorded on the bottom of your Scantron sheet. This is the number of points you have earned for correct answers well call this y.

You must now count up the number of questions you actually got wrong, not including questions that you skipped. The number of questions wrong will be z.

 

Divide z by 4 because the AP College Board deducts an extra quarter of a point from your grade for every question that you got wrong z divided by 4 = n.

 

Now, subtract n from y and multiply that answer by x. This is your new total point value (which well call a) for the multiple choice section of the test confused yet? Hang in there

 

Now you need to factor in the tests essay section. First, consider the fact that AP Exam essays are worth 50 total points, so divide 50 by the total number of essay points possible on our test. That number will be j. Take your total number of points earned on the essay section and multiply it by j that answer is b. Finally add a + b and your answer is your combined, total AP score. You can convert that score into a 1, 2, 3, 4, or 5 on one of the tables below, but if youre still confused, maybe this example will help:

 

Lets say you earned 41 (y) out of 60 points on the Scantron section. We know that x = 1.67. Now, you skipped 8 questions and got 11 wrong (z), so you divide 11 by 4 and get 2.75 (n). Now you subtract 2.75 from 41 to get 38.25. Multiply 38.25 by x (1.67) to get a a = 64 (round to the nearest whole number).

Next, lets say there were two essays, each worth 10 total points. We divide 50 by 20 j = 2.5. If you earned 7 points on the first essay and 6 on the second, add those scores together to get 13. 13 multiplied by 2.5 is 33 (again, round to the nearest whole number).

Now, a + b (or 64 plus 33) = 97. By checking the first chart below, you would see that, going by this method, you would have scored a 4 on the AP Psychology exam. And on the second chart below, youd see that this would count as an 89% as a marking period test grade. Not too shabby considering that 97 out of 150 points would normally be a 65%!

 

 

After using the above formula, use this chart to help you convert your test score into a final AP score. Keep in mind that a 3 is considered Passing by many colleges and universities, but you need to check with the schools that youre interested in to see what score, if any at all, they will accept for a Psychology credit. The ranges on this chart are approximately equivalent to the ones used on previous AP Exams. Cut-off points on actual AP exams can change from year to year, but these are the ranges that I will be using throughout the semester to give you an idea of how you would have done if you had taken the actual AP exam:

 

5

106-150

4

88-105

3

68-87

2

43-67

1

0-42

 

 

And here is the chart that will help you convert your combined score into a regular test score for me to enter into the gradebook. All scores are percentages since, in the gradebook, each test is worth 100 points.
