Frequently asked questions

How do I get a math certificate on Coddy?
Pick any math course and complete a section - finish every lesson and challenge in it. The certificate is generated automatically the moment the last lesson is done and added to your account.
Is a math certificate from Coddy accredited?
No. Coddy is not a school and does not award academic credit. What the certificate records is that you solved every problem in a section yourself, on a board that checks each step - a concrete, verifiable record of the work, which is what a tutor, a teacher or a portfolio can use it for.
Are Coddy's math certificates free?
Yes. Every certificate is free to earn, view, download and share. There is no paywall on any math lesson and no subscription needed for the certificate.
How does someone verify a math certificate?
Every certificate has a unique ID and a public URL. Anyone can paste the ID into the verifier on this page or open the URL to confirm it is genuine and see which section it was issued for.
Can I put a math certificate on LinkedIn?
Yes - the certificate page has a one-click "Add to LinkedIn" button, a downloadable PDF and a public link. Most learners add them under Licenses & Certifications.
How many math certificates can I earn?
One per section of every math course - five for algebra today: fundamentals, inequalities and absolute value, graphs and systems, exponents and polynomials, factoring and quadratics - with more courses as the space grows.
Do I need to finish the whole course to get a certificate?
No. Each section issues its own certificate as soon as you finish it, so your first one arrives after the first section, not at the end of the course.
What if I lose my certificate ID?
Sign in and open this page: every certificate you have earned is listed under "My certifications" with a link and a download button.
