Practice the exact content PSI puts on your Tennessee esthetics exam. Mapped to the official topic breakdown below — no guessing, no generic Milady-style filler.
Direct from the Tennessee Board of Cosmetology and Barber Examiners 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.
Tennessee 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.
Tennessee requires 750 training hours for esthetics, along with completing the PSI exam (written + practical). Minimum age is 16.
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 I've seen candidates fall into, especially with the heavy weighting of Scientific Concepts, is underestimating the depth required for Infection Control. It's not enough to just know what a disinfectant is; you need to understand contact times, proper mixing ratios, and the specific pathogens each method targets. PSI's questions often test your ability to apply these principles to real-world salon scenarios, so make sure you can differentiate between cleaning, disinfection, and sterilization for tools, surfaces, and skin preparation.
