Best way to calculate percentage for a test?

Hey, so I'm trying to figure out the best way to calculate the percentage for tests we take in my classes. Can you guys recommend a reliable method or tool that takes things like partial credit or bonus points into account?

Calculating the percentage for a test can be fairly simple, even when accounting for partial credit and bonus points. I'll outline a method you can use:

1. Determine your total earned raw points: Add up all the points you earned on the test, including any partial credits and bonus points you received. Make sure to note the maximum possible points for the test, excluding any bonus points.

Example:

Let's say you got 34 points out of 40 on a test, with an additional 5 bonus points for an extra credit question. Your total earned raw points would be 34 + 5 = 39.

2. Determine the adjusted maximum points: If the bonus points are additional opportunities to earn points that exceed the original maximum points, you should adjust the maximum points accordingly.

Example:

The original maximum points for the test were 40 but had 5 bonus points. If the bonus points are additional points, the maximum points remain 40. However, if the bonus points are extra credit that could be used to compensate for lost points, the maximum points would be 45 (40 + 5 bonus points).

For this example, let's assume the bonus points are additional points and not considered part of the maximum, so the adjusted maximum points remain 40.

3. Calculate the percentage: Divide your total earned points by the adjusted maximum points, then multiply the result by 100.

Example:

Percentage = (Total earned points / Adjusted maximum points) 100

Percentage = (39 / 40) 100 = 97.5%

So, your percentage score on the test would be 97.5%.

This method offers flexibility in taking partial credit and bonus points into account. Just make sure you correctly categorize bonus points as additional or extra credit when determining the adjusted maximum points.
