We just released a slug of grades, meaning that students who did not do well start thinking about extra credit options (good) and how they are calculated (ok, but better to spend time reviewing class material, blogging or actually earning extra credit). Any how, the calculations, and further to my last post about this: we cap extra credit at 10% (ie students can have added to their actual class grade a maximum of 10% extra). That means no matter how much extra credit they actually earn, we never add more than 10%.
That 10% is added using the extra credit option in Angel, which shows everything out of 100%. So 6% extra credit shows in Angel as 60/100 extra credit, and the maximum allowable is 100/100 = 10% added.
