About CertPrep Coach

CertPrep Coach is a free practice site for Microsoft certification exams. It started with the new Azure AI exams, AI-901 and AI-103, and will grow to cover more.

The goal is simple: practice that actually teaches. Every question explains why each answer is right or wrong, and your progress shows when you’re ready to book the real exam.

Free, with ads

The site is free to use with no account. It’s funded by advertising. Ads never appear next to answer choices, and advertisers have no say over the questions.

Who runs it

CertPrep Coach is run by Northstar Enterprise LLC. It is an independent site and is not affiliated with, endorsed by or sponsored by Microsoft.
