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.
Oklahoma 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.
Oklahoma requires 1500 training hours for barbering, 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); 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 frequent pitfall for Oklahoma barbering candidates is underestimating the depth required for the Scientific Concepts section. Because it's 30% of the exam, it's not enough to just know the basics of sanitation. You need to understand the different types of pathogens, how they spread, the appropriate disinfection levels for various tools and surfaces, and proper client and barber safety procedures in detail. Don't just memorize definitions; understand the 'why' behind each safety measure. Practice scenarios in your head: what do you do if a client cuts themselves? What if you drop a tool? Thinking through these practical applications will solidify your understanding and prepare you for the trickier questions.
