Practice the exact content PSI puts on your Colorado nail technology 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 600 training hours for nail technology, 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); Nail Technology Procedures (Manicure, Pedicure); Nail Enhancements (Application, Maintenance, Removal); Nail Anatomy and Disorders; Client Consultation and Service Preparation. 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 common pitfall I've seen Colorado candidates fall into is underestimating the depth of knowledge required for Scientific Concepts, specifically Infection Control and Safety. Because it's 25% of the exam, it's not enough to just memorize definitions. You need to truly understand the principles of disinfection, sanitation, and sterilization, and how they apply in every single service. Many candidates focus too much on the glamorous aspects of nail enhancements and procedures, then get tripped up by scenario-based questions on cross-contamination or proper handling of tools. My advice? Don't just read the material; visualize yourself in the salon, making those critical safety decisions. Think about why each step is important for protecting both you and your client.
