How Extra Credit Affects Your Grade
Extra credit adds points on top of earned points without increasing the total possible. This raises the percentage.
Formula
Grade Boost = Extra Credit Points / Total Points Possible x 100
New Grade = (Current Points + Extra Credit) / Total Points x 100
The impact is inversely proportional to total course points. In a 500-point course, 15 extra credit points add 3%. In a 1000-point course, the same 15 points add only 1.5%.
Example Calculation
A student has 87% in a 500-point course. The teacher offers 15 extra credit points.
- 01Current points: 87% x 500 = 435
- 02After extra credit: 435 + 15 = 450
- 03New grade: 450 / 500 x 100 = 90.0%
- 04Grade boost: 15 / 500 x 100 = 3.0%
