Certification Study App
Free for nowCertForge · Education · Certification study & practice tests
CertForge is a certification study app with study guides, a 500-question bank per certification, practice tests with realistic exam settings, and detailed results with per-domain breakdowns and answer review. It currently supports GH-300 (GitHub Copilot) and AZ-204 (Microsoft Azure Developer Associate), and adding a new certification only takes new data, so more exams are easy to add.
CertForge is a certification study app for people preparing for technical exams. It pairs a study guide with a 500-question bank per certification, practice tests that mimic real exam settings, and results that break your score down by domain so you know exactly what to review. GH-300 (GitHub Copilot) and AZ-204 (Microsoft Azure Developer Associate) are supported today, and the app is free during early access.
What's included
Study guides per certification
Each certification comes with a structured guide covering what the exam actually tests, so your reading follows the exam outline rather than a random path through the docs.
500-question bank per certification
Five hundred questions per exam is enough depth to practise every domain repeatedly without simply memorizing the bank.
Practice tests with realistic exam settings
Timed tests under realistic exam conditions. The first time you feel exam pressure should not be at the testing centre.
Per-domain results breakdown and answer review
After each test you see your score split by exam domain and can review every answer. Weak areas stop being a feeling and become a list.
GH-300 and AZ-204 supported today
Full support for the GitHub Copilot certification and the Microsoft Azure Developer Associate exam, both current and in demand.
New certifications only need new data
The app is built so a new certification only requires new content, not new engineering. That makes expanding the catalogue straightforward.
Who it's for
CertForge is for developers and cloud professionals with an exam booked or about to be booked: someone chasing the GH-300 to validate their GitHub Copilot skills, or working through the AZ-204 for the Azure Developer Associate certification. It suits people who study in the gaps of a working week and need every session to count.
It also fits teams. When several colleagues are working toward the same certification, a shared question bank and comparable practice-test results make it easy to see who is ready and who needs another week.
The problem it solves
Certification exams fail people in a predictable way: they studied the material but never practised the exam. Reading documentation builds knowledge, but it does not teach you to answer scenario questions under time pressure, and it gives you no signal about which domains are weak until the real exam grades you, at full price.
The common workaround is scattered practice questions of uncertain quality, with no structure and no measurement. You grind questions without knowing whether you are improving, and without a study guide connecting the questions back to the concepts they test.
How it compares
The default way to prepare for a certification is a patchwork: official docs for the theory, a video course for orientation, and whatever practice questions you can find for the final stretch. Each piece lives in a different place, none of them measures you, and the practice questions rarely resemble real exam conditions.
CertForge folds that patchwork into one loop: study the guide, drill the bank, sit a realistic timed test, read the per-domain breakdown, and go back to what is weak. Unlike prep approaches that treat every exam the same, the guides and banks are specific to each certification. During early access the whole loop is free, so it costs nothing to run it alongside whatever you use now and see which one moves your scores.
Frequently asked questions
Is CertForge actually free?
Yes, it is free during early access. Pricing may come later, but everything currently in the app is free to use.
Do I have to create an account or enter a card?
No card is needed, and you can try it without creating an account.
Which certifications are supported?
GH-300 (GitHub Copilot) and AZ-204 (Microsoft Azure Developer Associate) today, each with its own study guide and 500-question bank.
Will more certifications be added?
Adding a certification only requires new data rather than new code, so the app is built to grow. More exams are easy to add as the catalogue expands.
Are the practice tests like the real exam?
They use realistic exam settings, including timing, and results are broken down by domain with full answer review, so a practice score tells you something meaningful about readiness.
