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.
New Jersey 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.
New Jersey requires 1200 training hours for cosmetology, along with completing the PSI exam (written + practical). Minimum age is 17.
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.

A big one I see is underestimating the sheer volume and detail required for Hair Care and Services, even though it's 45% of the exam. Candidates often focus heavily on practical skills during their training and assume that translates directly to the written exam. However, the written test will dive into the *theory* behind cutting angles, the chemical reactions in perms, different types of rollers, and precise steps for various styling techniques. My advice? Don't just know *how* to do a service; know *why* each step is performed, the science behind it, and all the safety precautions involved. Go beyond simply recalling steps and truly understand the concepts of hair structure, product chemistry for different services, and client consultation for hair-related issues.
