After attending Xamarin University courtesy of Xamarin, I am now proud to have passed the Xamarin Certified Mobile Developer exam.
The certification process consisted of attending 12 live interactive lectures online and an exam which assessed you on all content covered in the lectures and above. The exam lasted for 3 hours and was made up of 150 questions based on all aspects of Xamarin, Cross-Platform, iOS and Android. The pass mark for the exam was a high 80%.
I am extremely happy to have passed the exam first time, and it certainly was a testing one. My tips for anyone looking to take the exam, read through as much of the developer documentation and work through all the samples provided to achieve the best outcome.
