Practice the exact content PSI puts on your Nebraska esthetics exam. Mapped to the official topic breakdown below — no guessing, no generic Milady-style filler.
Direct from the Nebraska Department of Health and Human Services 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.
Nebraska 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.
Nebraska requires 600 training hours for esthetics, 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, 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 common pitfall I've seen Nebraska candidates fall into is underestimating the depth of knowledge required for the Scientific Concepts section, particularly chemistry. Many focus too much on memorizing formulas or classifications without truly understanding how different ingredients interact with the skin or how various chemicals used in treatments work. Don't just learn what an alpha hydroxy acid is; understand its chemical properties, how it affects the skin's pH, and potential contraindications. This deeper understanding will not only help you answer those trickier chemistry questions but also make you a more confident and effective esthetician.
