Each month I get a report of majors studying in my department. As we have two "concentrations" (and old and new designations for each concentration) the report is a bit complex. Further, newly admitted students who have declared their majors are shown, even though they have not yet earned grades that appear in the "institutional GPA" column.

I calculate the average GPA, as well as students above and below certain thresholds for the two concentrations, but know that the empty GPA cells are causing inaccuracies.

I think the ISNUMBER function might help me sort this out, but in addition to overall GPA, I also need to ensure that only one concentration is being factored at a time.

The current formula for all students is =SUM(GPA)/STUDENTS where GPA is all GPAs including empty cells and STUDENTS is the number of majors.

When I parse that for the "best" students, I use =COUNTIF(GPA,">3.499"), and for students at risk, I use =COUNTIF(GPA,"<2.501") and =COUNTIF(GPA,"<2.0").

I have to learn how to add in the ISNUMBER so that empty GPA cells are ignored.

It gets a bit more complex when I want to look at the concentrations, because I'm only interested in ignoring the empty GPA cells associated with one of the two concentrations.

For example, the "best" students in one concentration (remember the multiple designations) are reported using =COUNTIFS(GPA,">3.499",CONCENTRATION,"=LCJ") and =COUNTIFS(GPA,">3.499",CONCENTRATION,"=LSJ"). Again, I want to eliminate any consideration of "new" majors in this concentration who have yet to post a GPA.

I welcome your thoughts and suggestions.
