MuleSoft Certified Developer – Integration Professional (Mule 3) Exam: Format

  • format: multiple-choice, closed book, in a testing centre or proctored online using a qualifying, external webcam
  • length: 100 questions
  • duration: 120 minutes (two hours)
  • pass score: 80 percent
  • language: English
  • the MuleSoft Certified Developer – Integration Professional (Mule 3) exam can be taken a maximum of five times, with a 24-hour wait between each attempt

Delivery Methods

You can choose to take the MuleSoft Certified Developer – Integration Professional (Mule 3) exam in-person at a testing centre or online using a web camera, administered via the Kryterion Webassessor testing platform.

If you choose in-person at a Kryterion Testing Centre:

  • over 1000 locations worldwide
  • onsite instructions
  • a test-taker guide

If you choose online using the Kryterion Webassessor testing platform:

  • requires a webcam – a laptop webcam can be used, an external camera is not required
  • requires internet connectivity with 1 Mbps upload, 1 Mbps download, jitter <50ms, ping <200ms
  • use the tool to determine your internet speed and reliability
  • online instructions
  • a test-taker guide

If you think your connection might be unreliable, we recommend you choose a testing centre instead. An unreliable connection may cause you to be expelled from the exam.

Exam Preparation

We recommend preparing in the following ways:

  • take the instructor-led Anypoint Platform Development: Fundamentals (Mule 3) and Anypoint Platform Development: Advanced (Mule 3) courses
  • get six months to several years of real-world development experience on various MuleSoft projects
