Practice the exact content PSI puts on your District of Columbia cosmetology exam. Mapped to the official topic breakdown below — no guessing, no generic Milady-style filler.
Direct from the DC Board of Barber and Cosmetology 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.
District of Columbia 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.
District of Columbia requires 1500 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: Hair Services (Cutting, Styling, Chemical); Health and Safety (Sanitation, Infection Control); Skin Care; Nail Care; DC Laws and Rules. 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 one I see is candidates focusing too much on just the "glamorous" aspects of Hair Services, like intricate styling, and not enough on the foundational science behind it. Because Hair Services is the largest category at 35%, PSI will test your understanding of things like hair chemistry for perms and relaxers, the principles of color theory, and the anatomy of hair. Don't just know *how* to do a service, know *why* it works the way it does. Understanding the underlying science will help you tackle a wider range of questions within this crucial section.
