About Professor Erica
Free, comprehensive video courses for industry certifications — built by a CISSP, CISM, and PMP-certified professional. No ads, no inbox capture, no upsells. Just answers, the moment you need them.
Why this exists
The cert prep market is dominated by paywalled course bundles, $40 practice exams, and YouTube channels that tease the answer and ask you to subscribe. That model gates expensive credentials behind expensive preparation, when the underlying material — exam objectives, vendor whitepapers, RFCs, NIST publications — is openly available.
This site is the alternative: domain-by-domain video coverage of every certification we cover, a cross-referenced glossary, and browser-based practice tests that run with no account and store progress only on your device. Adding a new certification track is pure marginal cost. Sustaining it costs effectively nothing.
What's in scope
The current cert tracks live on the homepage. The roadmap targets vendor-neutral and entry-level cybersecurity, networking, and IT certifications first — the credentials with the strongest job-market signal relative to their cost. Adjacent training (ASVAB prep, teaching credentials) is on the list when there's demand.
How it's made
Content is researched against authoritative sources — CompTIA exam objectives, ISC2 CBKs, NIST SPs, vendor documentation — then taught by AI-generated avatar hosts in a panel format. The avatars and voices are AI; the curriculum, scripting, fact-checking, and quality gates are human-authored by a credentialed author. Every video lists music attributions and an AI disclosure in its YouTube description.
What's NOT here
- Brain dumps. Real questions verbatim from a live exam violate every certification's non-disclosure agreement. The practice tests on this site are independently authored to test the same concepts without copying.
- Pass guarantees. Nobody can sell those honestly. Hours of focused study + practice questions + the official objectives = the only honest playbook.
- Affiliate funnels. No vouchers sold here, no Pearson VUE referral codes, no "sign up for my course" upsells.
