How you will use it

Practise the way that suits you

  • Learn as you go. Answer, read why straight away, then move on. No clock, no pressure.
  • Or sit it timed. A clock, no answers until the end, and two minutes a question, so you learn to pace yourself.
  • Score by topic. See which area let you down instead of one number out of a hundred.
  • Go back over it. Read every question again afterwards, right and wrong, with the full explanation.

Is it for you

Who takes MB-500

Developers extending the finance and operations apps

X++ and the extension model are nearly half the exam between them.

Consultants moving from configuration into code

It marks where configuring the product stops and extending it begins.

Integration developers connecting these apps to other systems

Entities, OData, business events and dual-write are a fifth of it.
