Quality certification prep shouldn't cost money. Practice questions are the highest-value thing you can do before an exam — and charging people who are already paying exam fees (students, career-switchers, people in lower-income regions) never sat right with us.
So CertBase is free, permanently. No investors steering it, and no training vendor it has to sell for. We're a small independent project, and that independence is the point.
Every question can be reviewed, discussed, and improved by people who've actually sat the exam. If you've passed one, you can give back:
- ✍️ Submit questions for an exam you've passed
- ✅ Review and improve existing questions
- 💬 Help moderate discussions and flag outdated content
→ Contribute at certbase.pro/contribute — contributors get acknowledged for what they help build.
