Every finals week in college followed the exact same stressful ritual: sitting in front of a messy spreadsheet at 2 AM, trying to figure out what score I needed on a 30% final exam to keep my 3.5 cumulative GPA. To make matters worse, different courses used different credit weightings, and half of the online tools I tried were either covered in intrusive ads, broken by math edge cases, or locked behind account paywalls just to calculate a target grade.
That frustration is why I built GradePoint Pro (gradepointpro.getinfotoyou.com), a free web app designed to let students and parents calculate semester GPA, track cumulative GPA across multiple grading scales, and solve target grade requirements without hassle.
Here is a breakdown of why I built it, the technical hurdles I ran into, the tech stack I chose, and the lessons learned along the way.

Most generic grade calculators assume every school follows a rigid 4.0 scale with standard letter-to-grade point conversions. In reality, academic institutions vary wildly. Some use 4.3 scales (where an A+ is 4.3), others use 5.0 scales for AP/Honors courses, and many use custom percentage cutoffs.
