Frequently asked questions
How do the certificates work?
When you complete all required lessons and assessments in a course, a verified certificate is issued to your account automatically. You can download it as a PDF and share it directly to LinkedIn.
What is your refund policy?
Paid courses are covered by a 30-day money-back guarantee. If a course isn't right for you, request a refund within 30 days of purchase and we'll process it, no questions asked.
What do I need to take the courses?
A modern browser and an internet connection. Coding courses run in-browser labs, so there's nothing to install - though local setup guides are provided if you prefer.
Can I learn at my own pace?
Yes. Most courses are self-paced with lifetime access. Cohort-based and live courses have scheduled sessions, clearly marked before you enrol.
Do you offer team or corporate training?
Absolutely - see CorpTrain for managed cohorts, admin dashboards, SSO, bulk certificates and volume pricing.
