The incredibly talented cellist beat a raft of other young gifted musicians to make the finals, which will be taking place on February 8 in Warwick, in front of an invited audience and a panel of judges.
Oliver will perform on stage a four-minute modern piece called Juli-O by the composer Mark Summer.
“I love the musicality of the piece,” said Oliver, who is working towards his Grade 8 cello examination.
“I believe I may be the only cellist in my age category, I think I will be up against lots of pianists, a violinist, and a clarinet player.
“I’m very proud that I’ve been nominated and I’m practising the piece I’ll be performing before I go to school and in the evenings.”
Oliver was nominated after sending a recording of himself playing Bach Cello Suite No 1.
The 12-year-old also enjoys acting and has a big part in the school’s eagerly anticipated production of Matilda.
When he grows up, he says he’d like to be either a doctor or a solo cellist in an orchestra travelling the world.
St David’s wishes him the very best of luck on February 8, and the school is very proud of his achievements!
