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 … we’ll 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 we’ll call “a”) for the
multiple choice section of the test … confused yet? Hang in there …
Now you need to factor in the test’s 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 you’re
still confused, maybe this example will help:
Let’s 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, let’s
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, you’d 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 you’re 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. Cutoff 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 
106150 
4 
88105 
3 
6887 
2 
4367 
1 
042 
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.
