I think we can conclude that he is a year above Harry.
1st: He doesn´t share a dormitory with Harry. 2nd: He doesn´t share Potions classes with him.--Rodolphus 14:09, February 9, 2011 (UTC)

- Agreed. Also, aren't NEWTs taken on the seventh year? -- 20:19, February 12, 2011 (UTC)
Yes they are. But the lessons taken in sixth and seventh years, preparing for the final exam, are called NEWT courses. (McGonagall to Neville, Half-blood Prince chapter in the book)--Rodolphus 20:24, February 12, 2011 (UTC)
We should change the article, then. Fay Dunbar takuing potions and Bem being in Harry's year also seem to be non-canon.--Rodolphus 13:36, February 13, 2011 (UTC)
Didn´t JKR say there are 40 students in Harry's year, 5 per gender and each house? Also, in CS, it is mentioned that Harry's dormitory door has a patch with only "second year" written on it, indicating it's the only second year dormitory---Rodolphus 13:46, February 13, 2011 (UTC)
That is not the only second year dormitory going by what it says in COS. From Chamber of Secrets on page 85(paperback): "They hurried up it, right to the top, and at last reached the door of their dormitory, which now had a sign on it saying SECOND YEARS. They entered the familiar, circular room..."
From what I understand, it was their old room and the sign had just been changed.
Sorry for the spoilers but from Pottermore Jo says "While I imagined that there would be considerably more than forty students in each year at Hogwarts, I thought that it would be useful to know a proportion of Harry’s classmates, and to have names at my fingertips when action was taking place around the school." To me it seems that Jo just wanted forty students names to have 'at her fingertips' and that the 'forty students to a house' was not a closed case. Also I read this information on a few websites:
"Q: How many students attend Hogwarts, and how many students per year per house?
A: There are about a thousand students at Hogwarts." 
So with 7 years worth of students and 4 houses and estimating it to an even number that would be 34 students per house per year.
Since there are five to a dorm I just always rounded it up to 40 which would make it 1200 students in the school, with forty per house per year. Of course, my personal preferrence doesn't count. However, Jo is saying that there are at least thirty to a house in each year.
Also and again this is just my opinion, I don't believe that the hat divided the students evenly. As I am to understand it, the hat sorts the students by which house it thinks they are best suited for. I don't think it counts five girls and five boys to one house and then the rest go to whatever slots are left.
(It is more than halfway down the page.)
Sorry if that isn't cited correctly. It's my first time citing anything.
