Click on your banner thing that says your grade. It will bring up your transcripts, the things that you have got points for and your questions and answers.
Under it, towards the top of your screen, it is yellow and will say how many more questions you can ask, answer, vote and bump to get the credits. That's where the core credits come from. You get 2 for asking, one for bumping, 1 for voting and 3 for answering. They are divided up and you get the set amount each day.
It will also say how many you've got total today, and under that it'll say ___ core credits/___extra credits with the amount of each you've gotten so far.
