How is grade distribution for CS 101?

I know it may differ term by term, but I want to know what kind of grade distribution is expected.

1.Do they only have A,B, and C? Or are grades more separated and have A+, A, A-, B+, and so on?

  1. How are they distributed? What percentages do students fall into each category?

If ‘expecting’ those is too hard, please tell me how it is in 2017 spring.

Thank you.

Go there, select UIUC, type in CS101. 36% of students get an A or an A+.
