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 1550 training hours for cosmetology, 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, 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.

One common pitfall I've seen is candidates underestimating the complexity of chemical services within the Hair Care and Services section. It's not just about mixing and applying. You need to deeply understand the chemical reactions involved in perms, relaxers, and hair coloring, including how different formulas interact with various hair types and previous treatments. Don't just know *how* to do it, know *why* it works the way it does. This understanding will help you troubleshoot and answer those trickier scenario-based questions.
