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.
Wisconsin 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.
Wisconsin requires 450 training hours for esthetics, along with completing the PSI exam (written + practical). Minimum age is 18.
Every SGS practice question is mapped to the same topic categories PSI uses: Scientific Concepts (Infection Control, Anatomy, Chemistry); Skin Care and Services (Facials, Treatments, Hair Removal). 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 pitfall for Wisconsin Esthetics candidates is underestimating the depth of knowledge required for the Scientific Concepts section, especially Infection Control. Because it’s such a large portion (55%), many students know the basics but struggle with the nuanced questions about disinfection levels, sterilization procedures, and the different types of pathogens. My advice is to go beyond just knowing definitions; understand the practical implications of each infection control measure and how it protects both the client and the esthetician. PSI loves to throw scenario-based questions at you, so think critically about how you'd apply these concepts in a real salon setting.
