Reverse Engineering Your College GPA
The Semester GPA Predictor performs two essential calculations for academic planning:
- Forward Forecast: Projects your new cumulative GPA based on your expected grades this semester.
- Reverse Target Engineering: Solves for the exact semester GPA needed to achieve a target cumulative threshold (such as 3.50 for Dean's List or 3.70 for Latin Honors).
1. Forward Projected Cumulative GPA Formula
Projected Cumulative GPA=
(Current GPA × Prior Credits) + (Expected Term GPA × Planned Credits)Total Prior Credits + Planned Semester Credits
2. Required Semester GPA Formula (Reverse Target)
Required Semester GPA=
(Target Cumulative GPA × Total New Credits) - (Current GPA × Prior Credits)Planned Semester Credits
Step-by-Step Calculation Breakdown
Step 1: Calculate Current Cumulative Quality Points
45 completed credits × 3.20 current GPA = 144.0 points
Step 2: Calculate Target Total Quality Points Needed
(45 prior credits + 15 planned credits) × 3.40 target GPA = 60 × 3.40 = 204.0 points
Step 3: Calculate Required Semester Quality Points & GPA
Required Semester GPA=
204.0 - 144.015 Planned Credits
=60.0 Points15 Credits
