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.
Illinois 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.
Illinois requires 750 training hours for esthetics, along with completing the PSI exam (written only). Minimum age is 16.
Every SGS practice question is mapped to the same topic categories PSI uses: Scientific Concepts (Infection Control, Anatomy, Chemistry); Skin Care and Services (Facials, Treatments, Hair Removal). 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 pitfall I see Illinois candidates fall into is underestimating the depth of questions in the Scientific Concepts section, especially regarding chemistry and anatomy. They might know the basics of infection control, but struggle with questions about the layers of the skin, muscle groups of the face, or the pH of various products. Don't just memorize definitions; truly understand the processes and relationships within the body and how chemicals interact. If a question feels like it's asking for more than a surface-level answer, it probably is.
