The problem

Manually weighting course grades by unit load makes it easy to miscalculate a semester average.

What I built

Built an editable course table and instant weighted-average calculation, then added a plain-language guide, formula example, and grading references.

Current outcome

The calculator is live at its own domain. Results are estimates; the university remains the authority on official grades and honors eligibility.
