Would-be-buyers fairly regularly ask us whether our exam aids cover the very latest features, not realising the official exams aren't based on the latest Creative Cloud updates. For example, the latest Photoshop Adobe Certified Expert exam is Photoshop CC (exam code: 9A0-354), and not Photoshop CC (2014).
In fact, the official exams are frozen before they are released. The only updates they receive are corrections when errors are discovered. This has always been the case. We also follow in similar fashion and only update if errors are discovered after a release, and only upgrade to the next version when the corresponding exam is upgraded.
We name the exam aid after the exam and, for good measure, add the exam code to each product page, so that you can verify which exam is covered by the exam aid.
You can also visit the Pearson VUE site and do a search for the latest available exams (click on the 'View exams' link in the right column once on the website). If you see one listed but cannot find it on the Examaids site (you can input an exam title or code into the Search tool), then we don't have an exam aid for it. For example, Photoshop CC 2014 (exam code: 9A0-XYZ), etc.
