Practice the exact content PSI puts on your Tennessee cosmetology 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 1500 training hours for cosmetology, 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, Safety, Chemistry); Hair Care and Services (Cutting, Styling, Chemical); Skin Care; Nail Care and Services. 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 see is candidates focusing too much on just the "how-to" for hair services and not enough on the underlying principles. For example, in chemical services, it's easy to just memorize the steps for a perm. But the PSI exam will often throw in questions about hair porosity, elasticity, or the chemical reactions involved. If you only know the steps and not the science behind them, you'll struggle with those tougher application questions that make up a good portion of the Hair Care section. Always ask yourself "why" each step is done, not just "what" to do.
