### AP Square Root Grading

For Advanced Placement courses, to respect the amount of difficulty and effort that you experience with these tests, I use a square root grading curve. This is the formula for your score:

Square Root (% of raw score * 10) * 10 = Gradebook %

For example, if you scored 40 points on an 80 point test:

Sqrt((40/80)*10) * 10 = 70.71

Then, to get the score that you will get in the gradebook, I take that percentage and multiply it by the maximum score of the test.

.7071 * 80 = 56.57

In the gradebook, for this 80 point test, you would have a 56.57, or a 70.71%.

Here's what a square root curve looks like. The closer you are to 100%, the smaller the boost you get.

### Test Corrections

When you get a test back in my class, **you are able to earn back half of the points that you lost by doing test corrections**. Here is the procedure for doing so.

- Take a look at your answer sheet and make a list of the questions that you missed on a separate sheet of paper.
- For each missed question, write the correct answer, and include EITHER the page number from the book that you found the correct answer on OR the reason why you missed the question. E.g., "I mixed up Buddhism with Confucianism" for a vocab question, or "p. 78" for a fact that you forgot or didn't study.
- If you have a bubble sheet (or a "scantron"), fill in the correct answers on the red side (the test was taken on the blue side). Fill in every question, not just the ones that you missed.
- Paperclip everything together and turn it back in to the basket.
- Your grade will be updated with the corrected score.

Note: For AP classes, I will square root the new corrected score (see above), and you will earn back half of the difference between your original score and the corrected score.
