Questions: In addition to the chapter end questions and a full-length Mock exam in the Mala Gupta book, I bought the official question set from Oracle (Kaplan) for the same exam. The question set was, certainly, useful but I thought it was a little expensive at $69. So, if you have cheaper options, then those might be better.
Exam Venue: For the exam, itself, I took the exam at the Oracle's own test centre/office in Delhi, India. It was a pleasant experience as everything was set-up already and had no issues. Compared to the Pearson VUE, the Oracle's official centres allow you to take a bottle of water with you, which is good. The only downside of Oracle's own test centres is the dates. They had only 2 days per month or limited days when you could take the exam while at Person VUE you could take the exam any day (Mon-Sat), even on short notice.
Exam itself: One of the things that I was worried about was running out of time. So, I was keeping an eye on the remaining time and, at every 10 questions, I would calculate a rough average of time I was taking to answer the questions making sure that I wasn't taking more than the average of 1.55 minutes per question.
In the end, actually, I had nearly 30 minutes to spare after finishing the exam. It might be a good idea to mark the questions for review if you are a little unsure about the answer. You may find a review useful if you have spare time left at the end of the exam.
