FAQ

Questions Class Rank Estimator owners ask.

  • 01

    How accurate are these estimates?

    The capability uses a normal distribution model, which is a mathematical approximation. While useful for estimation, it should not be used as an official academic record.

  • 02

    What inputs do I need for calculate_rank_from_gpa?

    You need the student's GPA, the school's mean GPA, and the standard deviation of GPAs in the school.

  • 03

    Can I use this to find out what GPA I need for a specific rank?

    Yes, you can use the estimate_target_gpa capability to calculate the required GPA based on your target top percentage.
