About the California Institute of Technology GPA
California Institute of Technology (Pasadena, CA) reports student GPAs on the 4.3 scale. The conversion from letter grades to numeric values is straightforward: A = 4.0, A- = 3.7, B+ = 3.3, B = 3.0, B- = 2.7, and so on, with F = 0.0.
Your overall GPA is the credit-weighted average of all your course grades. A 3-credit class affects your GPA three times as much as a 1-credit class. Use the "grade needed on final" mode if you need to plan a target grade in a specific course.
