How we review
Five things we check in every exam prep course
We judge every course on the same five criteria, so comparisons are fair from one exam to the next.
Content
Does the course cover everything on the exam, accurately and up to date, in a way that’s easy to follow?
Delivery
Is it well structured and easy to navigate, at a sensible pace, with quizzes, practice exams and other interactive tools?
Value
Is the price fair for what you get? We look for hidden fees, retake costs and what’s included at each tier.
Support
Can you reach an instructor, tutor or support team when you’re stuck, and how quickly do they answer?
Reputation
What do past students say, and how does the provider handle refunds, guarantees and complaints?
Why trust us
Built on official sources, not guesswork
Official sources
Every licensing fact traces back to the state board, statute or exam bulletin it came from, listed at the bottom of each guide.
Dated and rechecked
Each guide shows when it was last verified, and we recheck every page at least once a year, sooner when rules change.
Neutral comparisons
Providers are listed alphabetically until we’ve completed a review, and we tell you when we haven’t ranked them yet.
