Added Ads You can choose between a small ad at the bottom of the grades page, or a 5 second ad when accessing the GPA and grade calculator. Ads will be disabled during the last week of the semester. There is also a secret feature allowing you to disable all ads permanently. Ask your friends if they know how to activate it. You can now modifier and add class grades in the GPA calculator. There is a shimmer effect on the grades page if you have all As or A minuses.
