Questions were sometimes very tough, but OCP is a mean and wide-ranging exam, so you have to prepare yourself for all the pitfalls that may be waiting for you on the real exam.

After finishing I read all the exhaustive explanations - some of them covering more than a page, even for the questions that I answered correctly, then going back to the course books or the online Java API to look up what I may have missed. Eventually I passed the real exam with a 85% score, which was about 10% higher than my practicing average.
