In April 2015, I enrolled for the Salesforce Certified Force.com Advanced Developer exam and successfully did the multiple choice exam. Since then, the actual scheduling of a programming assignment was postponed until September, and when that window opened, I missed my chance to participate. This weekend I received an e-mail telling me that a new window has opened up, and that I will be able to register for a programming assignment soon.
In the meanwhile, the whole certification plan of Salesforce has been restructured, rendering most (if not all) of the certificates deprecated and replaced with new ones. I do not want to spend time and effort into an assignment that will only result in a certificate that will be obsolete in a few months. I did already pay for it, on the other hand.
