Are you studying for the Xamarin Certified Mobile Developer exam?  It’s a pretty daunting exam, there is just such a large amount of material covered.  So I thought I’d share my experiences and topics covered during my certification exam to help others on their way.

A study guide, if you will.

Disclaimer: The information I present here is only based on my exam experience.  My understanding is that the question set is pulled from a pool of questions – so maybe you’ll get some of these topics, maybe you’ll get something else all together Smile.  I also did the exam before the explosion of Xamarin.Forms so no doubt there will be lots of questions about that.

Number of Questions

150 multiple choice questions

Question Format

Multiple choice questions.  Most of the multiple choice questions were “choose the right answer” intermixed with a couple of “select all that apply” and a few “true/false”.

Exam Duration:

3 Hours (it took me the entire time)

Study Materials

  • The Xamarin University courses and tutorials / workshops in each session.  I would recommend doing each course twice if you have time.  It is definitely actually worth working through all the samples (and where possible extending them to challenge yourself).
  • Studyguide for Xamarin Mobile Developer exam – Kaj Bonafils has a good set of links into the Xamarin Documentation.
  • The Official Xamarin Documentation.  Not only is the Xamarin Documentation fantastic, I’m pretty sure just about everything in the exam is covered *somewhere* in the official docs.
  • Xamarin Forums: Lots of good information in here including this: Exam Study Guide?

    Hi,

    After completing all the live sessions, within how many days we will receive the examination link to attend the certification exam.

    Thanks

    1. Kym says:

      Should be pretty much straight away, it’s an automated email. Maybe give it a few days before contacting them. Also make sure you check your profile page to ensure you have completed all the requirements. Good Luck!

    Hi,

    Must we need to subscribe Xamarin University to attend this certification? I saw Xamarin University Subscription $999. How much it cost would be totally?
