About QuickGrade

Who I am
My name is Muhammad Umar. I build and maintain QuickGrade on my own — the calculators, the guides, the grading tables, and every correction that comes in through email. There is no team behind this site and no anonymous content agency; if a page here is wrong, it is my mistake to fix.
My background is in software, not classroom teaching. I started working on grade arithmetic while helping family members who teach middle-school and high-school subjects rebuild their gradebooks each term in spreadsheets. The same three questions came up over and over: what percentage is 43 out of 50, how do weighted categories combine into one course grade, and what does a student need on the final to keep a B. Those three questions are the reason this site exists, and they are still the three calculators people use most.
Why I built it
Most grading tools online are either a single number-cruncher with no explanation, or a wall of text with no tool. Neither helps someone who is confused about why their grade came out the way it did. So every calculator here shows the formula it uses, states its assumptions, and links to a guide that walks through the arithmetic by hand. If you can reproduce the result on paper, you can also spot the moment where your teacher's gradebook did something different — a dropped score, a redistributed weight, or a rounding rule.
I also keep the site deliberately plain: no accounts, no sign-up, no data collection on the tools, and nothing that gets in the way of a teacher grading a stack of quizzes between classes.
How the content is checked
Every calculator is tested against hand-worked examples and against published grading scales before it goes live, and I re-check the examples whenever a page is edited. The full process — what I verify, what I cannot verify, and how corrections are handled — is written up in how we verify calculations and in the editorial policy.
What this site cannot do
QuickGrade is an educational reference, not an official record. Schools, instructors, colleges, and districts use different grading policies, weighting rules, rounding conventions, and grading scales, and some of those differences change the final letter grade. Always confirm an official grade, transcript, or academic decision with your school or instructor before acting on it.
Contact and corrections
If you find an incorrect calculation, an unclear explanation, a broken link, or a grading scale that does not match your school's, please tell me. Send the page URL and what you expected instead — corrections from teachers are the single most useful email I get. Use the contact page or email ezgradersupport@gmail.com.
