When I took the exam in the summer of 2008 there were not any “essay” or comparison type problems. I am not sure if they still have those on exams anymore. I know that friends and colleagues that have taken the exam the past couple of times have not had any problems like that either.
That’s not to say they will not have one this go around. So to answer your question I have no idea if they have been removed or not. I just know the past year and a half they have not had one on the exam. I hope this helps and good luck!
