About these tools

The Educate section covers the math students actually need on a deadline: working out a GPA from course grades and credit hours, figuring out exactly what score the final exam requires to land a target grade, and everyday percentage calculations for assignments, discounts, and statistics.

Every calculator shows its work — the GPA tool displays the grade-point values and credit weighting, and the final-grade tool shows the formula it solves — so these double as a way to learn the method, not just get the answer.

Like everything on Tallyloom, the tools are free, need no account, and run entirely in your browser: grades and scores you enter are never uploaded anywhere.

Which one you need depends on where you are in the term. Use the GPA Calculator when you have final letter grades and credit hours and want a cumulative number; use the Final Grade Calculator when the term isn't over and you want to know what the exam has to deliver. The Percentage Calculator handles the one-off questions — what percent of, percent change, reverse percentages — while the Fraction Calculator keeps answers in exact fraction form instead of rounding to decimals. The Citation Generator formats sources in APA 7, MLA 9, or Chicago, and the Roman Numeral Converter reads dates on monuments, film credits, and outlines. The Flashcard Creator and Study Timer are for the work around the work: one builds a quiz deck from your own material, the other paces the sessions.
