Exam was easy compared to what I thought it might be.
I did not like the review of drag and drop questions. If you review a drag and drop based question, then all the previous answers are removed and you have to redo everything. Since review phase is usually towards the end of exam, it is bit risky to review those drag and drop questions if one can't finish them on time.
