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.
Missouri 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.
Missouri requires 1000 training hours for barbering, 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); Hair Cutting and Styling; Facial and Shaving Services; Chemical 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 depth of questions in the Scientific Concepts (Infection Control, Safety) section. Because it's tied with Hair Cutting and Styling at 30%, students often focus heavily on practical skills and assume they've got the safety stuff covered. However, PSI questions can go beyond basic definitions. They might present scenarios where you need to apply infection control principles to a specific situation, or ask about the proper handling and disposal of various chemicals. Don't just memorize; understand the "why" behind each safety protocol. Imagine you're explaining it to a client – that level of understanding will help you ace those questions.
