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.
Maryland 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.
Maryland requires 250 training hours for nail technology, 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, Chemistry); Nail Technology Procedures (Manicure, Pedicure); Nail Enhancements (Application, Maintenance, Removal); Client Consultation and Nail Service Preparation; Post-Service Procedures; Nail Disorders and Anatomy. 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 frequent stumble for Maryland candidates is not digging deep enough into the "why" behind the Scientific Concepts. Because it's the highest-weighted section at 25%, simply memorizing terms for infection control or chemical safety isn't enough. The exam often presents scenario-based questions where you need to apply your knowledge, not just recall it. My advice? When you're studying chemistry, don't just learn what monomers and polymers are; understand how they interact and why certain ventilation is necessary. For infection control, think about cross-contamination risks in every step of a service. This deeper understanding will serve you well on the exam and keep your clients safe in your future career.
