I just took the exam… I’m going to share my thoughts on it elsewhere; this post, however, is to warn about an unexpected behavior of the exam that can signfigantly impact your score.
As per general exam best practices, I “skipped”* some questions, intending to return to them once I finished all the other questions. After answering the last question, I started going in reverse order from question 90 to 89 to 88, etc. (unfortunately, navigation to a specific question is not available). I changed the answers to questions I skipped and continued going in reverse order. Only as time was running out did I realize that clicking the “previous” button (which I did to continue going in reverse order) does not save changes made to the answer!
Takeaway: If you change an answer on the Bubble Developer Certification exam, click “Next” to save your change even if you want to go to the previous question (which you can navigate to after clicking Next by clicking the previous button 2x).
*not a true skip as some answer is needed to go to the next question
