Are the courses free?

Yes. Every course here is free to take in full. Where a platform also sells a paid certificate, we link to the free version, and the course page says so.

Do I get a certificate?

Not from Gratis Global. We catalog learning materials, not credentials. Some platforms offer a certificate as a paid extra; that is their option, never a requirement to learn.

Can I learn at my own pace?

Yes. Every course here is self-paced. The lectures and materials are always available, so you can start any time and take as long as you need.
