Practice the exact content PSI puts on your California esthetics 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 600 training hours for esthetics, 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: Skin Care Services (Facials, Treatments); Health and Safety (Infection Control, Anatomy); Hair Removal and Lash/Brow Services; Makeup Application; Chemistry and Product Knowledge. 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 common pitfall I've seen with California candidates is not thoroughly understanding the "why" behind their Skin Care Services practices. It's not enough to just memorize steps for a facial; you need to grasp the anatomy, physiology, and contraindications. For example, knowing *why* a certain product is used on oily skin or *why* you avoid a particular modality for someone with rosacea. PSI’s questions often go beyond simple recall, asking you to apply your knowledge to client scenarios. Really dig into the underlying science of each treatment you learn.
