Mico will get an opportunity to defend their intercollegiate title after a comprehensive, ten-try 54-7 semi-final win over UTech.
The teachers-in-training were led by full back Kennard Woolery who scored a 24 points from a hat trick and six goals.
UTech showed great resistance early in the game but after losing inspirational hooker Adrian Nicholson to an ankle injury on 20 minutes, were effectively out of the contest.
Jamaica national player Jakeba Grant scored all their points from penalty kicks and a drop goal.
Toyin Cross and Antonio Barber each grabbed a try double and there were touchdowns for Joel Simmonds, Astil Johonson and Alec Harris; Damone Downer with a conversion for Mico.
After beating UWI twice already this season, few would have thought GC Foster had any chance of losing to their long time rival in the other semi.
However, a brilliant hat-trick of tries from Bahamian speedster Jordon Isaacs returned UWI to the finals for the first time in three years with a 36-12 success.
UWI was in charge of the game from start to finish with good use of their forwards to control the middle and their speedsters finishing off well planned moves out wide.
Mike Williams with a brace, Shannon Harris and Jade Harris were their other try scorers, Kemoy Whyte with four goals.
Percival Rose and Adrian McKenzie posted four pointers for GC Foster, Stephen Scott on target with two conversions.
The Grand Final will be held on Thursday April 17 at 4pm at a venue to be announced, there will also be a third place play off.
