hey,
are we talking about the mcat. i am pretty sure that there are only two, two essays to do and a half hour to do each one.
the jist for the scoring is that there are two grader who grade it from 0-6, if a person gets all threes they are going to be about average with a P. the scoring range is from J(junk) to T(terrific). i imagine that one would really not have a problem as long as they had at least a M or a N. The format is the same for each question, one just has to answer the question logically and complete all of the requirements for the essay, if that is done, a 3 from the graders is very likely. once you take a look at a couple of the samples you will understand how it goes. it really is an easy section, if you have had to write any essays in highschool or college, you should be pretty well prepared.
