Why we built it
The people studying for a named technical certification — with a real fail-cost and an exam date on the calendar — were being served either dated question banks or, worse, scraped "exam dumps" that teach nothing and risk a ban. Neither tells you what you actually know.
We started from the opposite end: a practice exam that behaves like the real thing, scores you honestly against the published blueprint, and turns that score into a plan. Find the weak domain, drill only the gap, retest, and watch the number move. That loop is the entire product.
What we make
A free desktop and phone app, and a catalogue of paid packs that run inside it — test banks, referenced study manuals, guided courses, and bundles. We started with the NVIDIA-track certifications for AI infrastructure and generative AI, and have expanded across vendor-neutral AI and the major cybersecurity certifications.
How questions are made
Every item is authored by a practitioner who holds the certification, written from primary documentation, given a worked explanation and a citation, and signed off by a second reviewer before release. Revisions are dated and version-controlled, and updates are free for the life of the pack.
Measurement first
A score you can trust is the product. Everything — blueprint weighting, domain maps, attempt history — exists to tell you the truth about where you stand.
Original & referenced
Every question is written from primary documentation, explained, and cited. We do not scrape, leak, or resell live exam content. Ever.
Independent by design
We are not affiliated with or endorsed by the certification bodies we prepare you for. That independence is the whole point — we answer to learners, not vendors.
Own it, don't rent it
Buy a pack once and keep it, updates included. No subscription stands between you and a practice test.
