Taking the exam
The certification consists of 40 questions. Each question is worth 1 point. Questions have two to four possible answers. The tricky part is that it is multiple choice. That means – all of the answers can be correct. Or none of them. Or any combination. That usually makes guessing really hard. You are allowed to use Vaadin Documentation and Java Doc freely, it is not considered cheating. So it is really useful to have them at hand during the exam. However, each question has a strict time limit of 90 seconds. That is not enough to search for a verification of all the possible answers. You need to know what is the question about, but you can usually verify one or two answers you are not so sure about.
If you run out of time for a question, you continue to the next one. You can move only forward, there is no way to check back your previous questions. If you take as much time as possible for each question, the exam will take nearly one hour, but usually, it can be done faster.
Pausing the exam
When taking the exam, make sure your connection is as stable as possible. However, if you happen to lose the connection during the exam, nothing is lost. You can continue the test later when you manage to reestablish the connection, however, the last question will be marked as incorrect.

Vaadin 7 vs 8
The exam is just an updated version of previously available Vaadin 7 certification. That means, if you’ve already passed the previous exam, you will be more than familiar with the format and contents of the test. Many questions are very similar to what was available in the previous version and it should not be too hard to prepare for the updated exam if you already passed the original one.
