Practice the exact content PSI puts on your Colorado cosmetology exam. Mapped to the official topic breakdown below — no guessing, no generic Milady-style filler.
Direct from the Colorado Office of Barber and Cosmetology Licensure 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.
Colorado 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.
Colorado requires 1800 training hours for cosmetology, 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, 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.
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.
Many Colorado cosmetology candidates fall into the trap of only focusing on the "fun" aspects of Hair Care and Services, like elaborate updos, and neglect the foundational chemical processes. While styling is glamorous, the chemical services (perms, relaxers, color) often involve more complex scientific principles and safety protocols. Because Hair Care is 40% of the exam, and a significant portion of that includes chemical knowledge, a common mistake is not deeply understanding the chemistry behind these services – what products do, how they interact with hair, and critical safety precautions. My advice is to dedicate extra study time to the chemical aspects of hair, understanding pH, product ingredients, and proper application techniques to avoid over-processing or damage. Don't just know *how* to color, know *why* the color works the way it does.
