The proof is in the numbers

Not new. Not experimental.
Proven under pressure.

When COVID-19 closed every school in Ireland, Carl Lynch and Gerry Walsh moved everything online immediately — and gave every grind for free. At the peak, 345 students joined a single live class. That's not a Zoom call — that's a full lecture theatre, delivered online, with no notice.

Those students didn't just survive the pandemic. They came back the following year and paid — because the quality was that good. We've been delivering expert online Maths grinds since 2020. We know exactly what works.

🔒 Proven since 2020 · Built when it mattered most

Who teaches your child

Two teachers.
One remarkable story.

This isn't a tutoring marketplace. These are two real teachers with a 33-year connection — and a shared belief that every student in Ireland deserves access to the best.

Carl Lynch
Founder, Revise.ie · HL Maths Teacher
33 years teaching Revise.ie founder HL Maths specialist

Carl has been teaching Higher Level Maths for 33 years. He founded Revise.ie 19 years ago because he believed students outside Dublin deserved the same quality of teaching as everyone else.

During COVID, he moved everything online overnight and gave every grind for free. At the peak, 345 students joined a single live class. Those students came back the following year and paid — because the quality was that good. The same standard you get in the room at the Ormonde Hotel in Kilkenny is what you get online. Not a stand-in. The real thing.

Gerry Walsh
Maths Teacher · Revise.ie
12 years experience Carl's former student COVID online pioneer

Carl taught Gerry in school. Gerry went on to become a Maths teacher — at the same school as Carl — and then joined Revise.ie, teaching alongside the man who taught him. That's not a hiring decision. That's a legacy.

When COVID hit, Gerry didn't wait. He was in those massive live classes — delivering Junior Cert Maths online to hundreds of students, for free, when every school in Ireland was closed. 12 years experience. Carl's methods. His own talent. Your child gets both.

They're simply offered on different nights. Both cover 6 key topics, Proof night, Construction night, and the nights before Paper 1 and Paper 2.
Every single session is recorded in full. The recording appears in the student's TrainerCentral account as soon as the live class ends — watch it that same evening, the next morning, or the weekend before exams. Nothing is ever lost.
