Exam technique is as important as technical knowledge when sitting the prometric OCP test.

If you look at this question again and first eliminate the completely wrong answers it will help. So in this case you know that interval implies something to do with blocks so that means both A and D can be eliminated immediately as time is not involved. That means you have already given yourself a 50/50 chance on this question. Next if you think about the idea of an 'interval' in terms of blocks you can also eliminate B.

If you get 10-15 questions like this in the exam and use this technique you should get at least 7-8 correct.

This tip might seem like common sense but quite a few people don't get it.

Good luck with the exam.
