I've rearranged the forums, etc under categories for specific years, to make things more navigable (although the phpbb software is still rather antiquated -- I'm hoping for the new version soon, if you have suggestions please reply.) You should be able to link directly to a category, which collapses all other categories, making the initial page less overwhelming.
Unfortunately this removes the initial concept of keeping courses grouped by function - such that they might be considered within the scheme of a student's education as a whole and less a part of a particular "year" of study -- a notion which implies that particular years require distinct course structures to be effective.
Of course any site admin can revise as they wish. Interested?
