I was able to do it with short answer ans essay questions, but they were on subjects I was already familiar with (my major) and I already could communicate with my unconscious from my previous training.
Even then, I did run into a problem the first time by the way I phrased the question. All I did was ask my unconscious to give me correct answers to the question and it did, but I should have asked for answers that were correct in the professor's model of the world. That is also a good idea when you are working on essay questions anyway.
