Practice the exact content PSI puts on your California nail technology exam. Mapped to the official topic breakdown below — no guessing, no generic Milady-style filler.
Direct from the California Board of Barbering and Cosmetology and the PSI candidate bulletin.
Your SGS dashboard tracks your score in each of these categories so you know exactly where to study.
The tools students use every night in the 30 days before their test.
California uses the PSI exam, which requires 75% or higher to pass. Practicing at least 10% above that on SGS mock exams is the sweet spot students who pass on the first try hit.
California requires 400 training hours for nail technology, along with completing the PSI exam (written only). Minimum age is 17.
Every SGS practice question is mapped to the same topic categories PSI uses: Nail Care Procedures (Manicure, Pedicure); Health and Safety (Infection Control, Chemistry); Nail Enhancements (Acrylic, Gel, Wraps); Nail Disorders and Anatomy. Your progress dashboard shows which categories you're strong in and which need work before test day.
Yes. SGS works in any mobile browser — no app install required. Flashcards, practice tests, and The Final Look exam all work on iPhone, Android, and tablet. Save your seat in The Lounge to sync progress across devices.
A big one I see candidates make, especially with Nail Care Procedures being such a high percentage, is rushing through the infection control questions. They assume it's just common sense. But PSI will throw very specific scenarios at you regarding proper disinfection times, EPA-registered products, and cross-contamination. Don't skim these; know the exact protocols for every tool and surface as if your license depends on it – because it does!
