The rules for using this site, and the limits of what our results mean.
Last updated: 2 August 2026
By using Examfo you accept these terms. The calculators are provided free of charge for personal, educational use. You don't need an account and we don't require anything from you in return.
This is the important one. Every figure produced here is an estimate for your own planning. It is not an official record and carries no authority. Conversion formulas, marking schemes and grading rules are set by boards and universities, differ between institutions, and change by regulation year.
Before using any number from this site on a transcript, job application, admission form, scholarship application or government form, verify it against the figure your school, board or university officially issues. Where we know that published sources disagree about a formula, we mark it on the page, but the responsibility for checking rests with you.
The site and its calculators are provided "as is", without warranty of any kind. We work hard on accuracy and test the maths, but we do not warrant that every formula is current or correct for your specific institution and regulation year.
To the extent permitted by law, we are not liable for any loss arising from use of this site, including decisions made on the basis of a calculated result. Nothing here excludes liability that cannot lawfully be excluded.
Please don't attempt to disrupt the site, scrape it at a volume that degrades it for others, or republish its content wholesale as your own. You are welcome to link to any page, quote a short passage with attribution, or use a shared calculation link.
The design, written content and code of this site belong to us. The underlying conversion formulas are published by the relevant boards and universities and are not ours, we simply implement them and say where they come from. Names of boards, universities and examinations are used for identification only; we are not affiliated with, endorsed by, or connected to any of them.
The site is supported by advertising. See the privacy policy for how advertising cookies work and how to opt out.
We may update these terms; the date above will reflect that. Continuing to use the site after a change means you accept the updated terms.
