Why can't I find a certain class?

UCI might be withholding that class's data, or the instructor may have submitted grades late so the data wasn't collected in time. UCI doesn't release grade distribution data for classes with 10 students or less.

Why can't I find a certain instructor?

There are 3 possible reasons:

• If they are a professor/lecturer, it may be for the same reasons as "Why can't I find a certain class?" above.
