Colaiste Chriost Ri got their Corn Ui Mhuiri campaign off to the best possible start with a 2-12 to 2-6 victory over St Flannan's at Kilmallock, and now only need a point from their game with Colaiste na Sceilge to be sure of a place in the last eight.
Only three points separated the sides at half-time, 1-6 to 1-3 in favour of Chriost Ri -- Barry Lynch's goal keeping St Flannan's in contention -- but with their captain Conor Horgan hitting 2-7 and Stephen Cronin in dominant form, the Cork school ran out comfortable winners.
Holders Pobalscoil Chorca Dhuibhne served notice that they won't give up their title easily with a 4-22 to 0-3 victory over North Clare Schools at Rathkeale.
The Kerry school, 2-10 to 0-2 ahead at half-time, laid the foundations for their victory at midfield, where Enna O Conchuir was very prominent. Their forwards thrived on the plentiful supply of ball that came their way and goals by Cathal O Bambaire and Pol O Breathnach endured a comfortable victory for the holders.
Elsewhere, Rochestown College got their campaign back on track with a comfortable 5-12 to 1-6 victory over West Clare Schools at Bruff. The victory means the Cork school must now beat IS Killorglin in their last round-robin tie to be certain of reaching the knock-out stages.
Sean Murphy at full-forward did the bulk of the scoring for the winners, who also had excellent players in forwards Cathal Cormac and David O'Connor and midfielder Andrew Murphy.
West Limerick Schools eased past Clonmel HS at Ballybricken on a scoreline of 1-9 to 0-9 to keep their knock-out hopes very much alive.
The game's only goal came midway through the first half and was scored by Jamie O'Connor and helped his side to a 1-6 to 0-5 half-time lead. They held that advantage throughout the second half thanks to the efforts of Darren Jones and John Murphy. Despite the defeat, Clonmel are still in with a chance of qualification but must beat the holders Chorca Dhuibhne in their last game to do so.

In a totally one-sided affair, the Mid Cork school led 0-4 to 0-1 at half-time. Rock-solid in defence, where their half-back line of Adam Kelly, Sean Kelleher and Shane Creedon were unbeatable, denied ISK a score for 35 minutes play.
The dominance of midfield meant a plentiful supply of ball into their forward line, where Pa Lucey racked up five points, John Murphy chipped in with two and, while he didn't score, Padraig Berhanu also played a key role.
