Why I built Pass-IT around questions and explanations

How my AZ-900 preparation shaped Pass-IT: short practice sessions, explanations, AI follow-up questions, and scores that help you decide what to review.

I built Pass-IT while preparing for Microsoft’s AZ-900 exam. I wanted to practice on my phone in short sessions, with enough explanation to understand why an answer made sense. That combination became the starting point for the product.

I’m David Braun, a product manager and father of two in Zurich, Switzerland. Pass-IT is self-funded, and I operate it as a Swiss sole proprietorship. You can find those details on the about page. Here, I want to explain the choices behind the learning experience and what you can reasonably expect from it.

What comes after an answer

A practice question gives you a decision to make. The explanation is where you can examine that decision: which part of the question matters, why one option fits, and what makes another less suitable. I wanted that reasoning to be part of the practice itself.

For example, after answering a question, try explaining your choice before reading the explanation. Then compare the reasoning. A correct answer can still leave you with something to investigate if you chose it for the wrong reason. If a distinction remains unclear, you can ask Alex, the AI tutor, a follow-up question about that specific point. The method page explains the approach further.

How the questions are made

Pass-IT uses an existing bank of original practice questions, created with AI assistance and reviewed. These are practice materials, not questions taken from actual exams. Alex also provides AI assistance; its answers deserve the same careful reading as any other explanation.

Checking sources matters, but a source check does not make a changing fact permanently correct. Services and exam information can change after a question has been reviewed. When your understanding depends on a current feature or requirement, check the relevant provider documentation. The quality page explains how we approach the question bank and its limitations.

What the score is for

The readiness score draws on your practice results to help you choose what to review next. It does not predict whether you will pass, and it is not a probability of passing. I want it to support a practical decision: which topic deserves another look, and which explanation should you revisit?

Pass-IT is available on iOS and the web, including through an Android browser. You can browse the certification catalog and start with a limited free session without a payment card. That first session gives you a way to try the practice and explanations; it does not include all Pro access. Use it to see whether this way of working through questions suits your preparation.
