# FAQ

## What is CollegeSlate?

It's actually **really simple**: we get raw grade data from the **University of Colorado at Boulder** and present it in an understandable format so you can make informed decisions about what classes you should take, and which instructors you should take them from.

## Where did CollegeSlate's data come from?

CollegeSlate's raw data is collected directly from the **University of Colorado at Boulder**, and because of that, it's comprehensive, accurate and free of bias. In other words, our data comes from *real grades* received by *actual students*, as reported by the *university itself*. We provide access to the complete grades of **44,287 classes** over **15 semesters
** at CU - that's **1,652,583 grades** in total.

## Do you know individual students' grades?

Definitely not. The grades we get from the university are on the class level. That means we know what grades a particular instructor gave in a particular class, but not *who* received these grades.

## How do you calculate GPA's?

We take the number of A's, B's, C's, D's and F's given in a class or by an instructor, multiply by the point value of each grade (i.e. an A is worth 4.0, a B is worth 3.0, etc) and then divide by the total number of students who received a grade in that class. Students who dropped the course, took an incomplete, or took the course pass/fail are excluded from the calculations.

It's worth noting that, although the University of Colorado assigns student grades with pluses and minuses, they *do not* report this information to us, so we can't factor it in to our grade calculations.

## Do you have data for other universities?

Not at the moment.
