Tell me about the Credit/No Credit (a.k.a. Pass/Fail) system.
For some classes (depending on your school and major), you can choose to bypass the regular A-F grading system and elect the Credit/No Credit option, often referred to as pass/fail. You sign up for it at your school office between the 21st and 30th day of the Fall & Spring semester, specific dates are posted on the KU academic calendar. Here's how it works:
If you earn an A, B, or C in that class, your grade report will show a simple CR, meaning that you've received credit for that class. However, if you earn a D or F in the class, then you'll get no credit at all, an NC on your grade report. The CR and NC do not affect your GPA in any way.
