Mission
Every certification course you'd pay $400+ for, taught for free.
Cert prep is dominated by paywalled course bundles, $40 practice exams, and YouTube channels that
tease the answer and ask you to subscribe before the explanation. Professor Erica is the alternative:
complete domain-by-domain video coverage, an open glossary that explains every acronym in plain English,
and a practice test bank that runs entirely in your browser. No accounts. No tracking. No lock-in.
Built to actually get you certified, then get out of your way.
