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.
Iowa 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.
Iowa requires 325 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: Nail Care Procedures (Manicure, Pedicure); Health and Safety (Sanitation, Infection Control); Nail Enhancements; Nail Anatomy and Disorders. Your progress dashboard shows which categories you're strong in and which need work before test day.

A big pitfall I see Iowa candidates fall into, especially with the 30% focus on Nail Care Procedures, is rushing through the practical steps in their minds. They might know *what* to do, but forget the *why* or the specific order. For example, during a pedicure, forgetting to check for contraindications or improperly sanitizing tools between clients can cost you points. The PSI exam isn't just about knowing the steps; it's about understanding the practical application, safety, and client communication throughout the entire service. Practice verbalizing your steps and the safety considerations as if a client is in front of you.
