About Prepdex
I built Prepdex to help my girlfriend pass her esthetician exam while she was working full time. She didn’t have hours to waste on material that wouldn’t be on the test — she needed to focus on exactly what mattered so she could pass and start the next chapter of her career.
That’s what Prepdex does. It figures out where your gaps are, builds a study plan around them, and tells you what to work on each day. No guessing, no wasted time.
Since then, over a thousand students have used Prepdex to prepare for their licensing exams. We think it can help you too.

How Our Content Is Built
Official exam blueprints
Every study plan starts from the official exam blueprint or content outline published by the licensing authority. We map the exact domains, weights, and topic areas so your plan mirrors what’s actually on the test.
Curated question banks
Questions are written to match the format, difficulty, and topic distribution of the real exam. Each question includes a detailed explanation so you understand the “why,” not just the answer.
Spaced repetition engine
Your study plan uses spaced repetition — an evidence-based scheduling method that shows you material right before you’d forget it. The system adapts to your performance, spending more time on weak areas and less on topics you’ve mastered.
Free practice questions available for every exam.
