I took the 6011. The 6011 is 100 mc and 7 essays, the 6990 is 120 mc and 4 essays. I used the ets practice praxis test to help me prepare. You have to answer questions as an administrator and not a teacher. Also, for the essays, get right to the point with answers. You don't need long drawn out answers. Use bullet points when answering. This will save you valuable time.
