|This is one of my biggest gripes about the manga too. I realize that what the mangaka is doing is writing to the current season, so to speak. (Spring stories in spring, summer stories in summer, etc...) But it is maddeningly hard to figure it out.
My best guess is that a the current point in the manga (as of Chapter 66) they are in their 3rd year finally and approaching 18. (I think they were 16 at the beginning but I seem to recall seeing them listed as 17 now...)
Spoiler (mouse over to view)
This is partly because the girl directing the movie in this arc is the Vice President of the club, so she has to be a 2nd year now, since she would have had to have been elected Vice President after being in the club for a year... So I think that the most recent spring stories, including Mysterious Petal, were really the beginning of their 3rd year...
[EDIT: I just checked one of the chapters, and their classroom is still "2-A", so my analysis is fatally flawed! The mangaka just doesn't bother aging them! They are stuck in class 2-A forevermore!]
Incidentally, the anime director seems to be doing a bang-up job of fixing this problem! He is telling a coherent story, putting the chapters in a logical order by seasons and topics, and totally getting the tone and even details of the story completely right, while fixing things the mangaka either failed to pay attention to, didn't care about, or really messed up! (The fan service levels are also really well done! Just the right balance of eechi and "awwwwwww, so sweet"!
