SOLUTION: if i have a 68% and i turn in a 20 point project and i get a 100% what would that raise my grade too?

You can put this solution on YOUR website!
You have to know what percentage of your final grade is the project.

Assume 25%

Your formula would be:

.25 * project grade plus .75 * the average of your other grades = final grade.

Assume this percentage is correct, then your final grade would be:

.25 * 100% + .75 * 68% = 76%

Your answer will vary depending on what percentage of your final grade is assigned to the project.

If a 20 point project means it's worth 20% of your grade, then adjust these figures accordingly.

This is a question that your teacher would be in the best position to answer.
