The Azure AI Fundamentals certification changed. The exam behind it is now AI-901, updated in April 2026, and it is not the paper it used to be: over half of it is now hands-on work in Microsoft Foundry, and the old service-by-service questions are gone. This app was rebuilt for that exam, not patched from the old one. What's inside: 75 questions Identify AI concepts and capabilities: responsible AI principles, how generative AI models work, choosing an appropriate model, and recognising which workload a scenario calls for. Implement AI solutions with Microsoft Foundry: prompt agents and hosted agents, the Foundry portal and SDKs, model deployment, and extracting information from documents, images, audio and video with Azure Content Understanding. One in-app purchase unlocks all 150 in this app, with no subscription. Every answer explains the rule Not just which option was right, but why and why the others were not. You get better instead of just scoring. Nothing here is out of date Questions referencing retired products were removed rather than reworded. There is nothing on LUIS, Text Analytics, Form Recognizer or QnA Maker, because none of them is on the current exam. Each question carries a Microsoft Learn reference so you can read further. Built for flights Everything ships inside the app. Nothing is fetched, nothing streams, nothing checks an account on launch, so airplane mode, the subway and a dead-zone basement all behave exactly the same as full signal. Also included Timed Pace Mode: an optional, non-enforced ~1 min/question countdown. It never locks you out and never auto-submits. Daily study reminder, if you want one. Scheduled on your device; nothing is sent from a server. Progress tracking: streaks, best scores and history, stored on your device. No account, no sign-up, no ads.

Built for owners, restorers, racers and the shops that look after them — from the 1959 Austin Seven to the 2000 Rover Mini. ASK DIY MINI BOT Type a question the way you'd ask at the club night. DIY Mini Bot answers from Classic Mini DIY's own data — torque specs, clearances, SU needle profiles, gearbox and compression maths, wiring diagrams, chassis and engine number decoding, paint colours, wheels and the parts archive — and shows the channel's video on the job when there is one. Claude orchestrates the tools; the Classic Mini knowledge is ours. • Ask from any calculator or reference screen — your numbers go with the question • 20 questions a month free with an account; Sustaining Members get more and keep their history synced with classicminidiy.com • It is an AI assistant and it can be wrong. Check safety-critical work against the manual. CALCULATORS Compression Ratio — bore, stroke, head cc, gasket, deck height and piston dome or dish. Pick pistons and gaskets for a street or race target. Gearbox — final drive, gear set, drop gear and tyre size to road speed at every rpm. Compare rod-change and magic-wand set-ups before you buy. SU Needle Guide — hundreds of needle profiles for HS2, HS4 and HIF44 carburettors, with charts to compare fuelling across the range. REFERENCE Torque Specifications — engine, gearbox, suspension, brakes and body fasteners in lb-ft and Nm.
