How to write a proof
The part of Junior Cycle geometry students lose most marks on, taught properly — definitions, the five axioms, then how to set a proof out so it earns full marks.
Watch back any time
Every class is recorded to the platform, so a clash with training or a match never costs a topic — and 3rd Years can go back over 1st and 2nd Year material before the exam.
The same teachers who take Leaving Cert
Tracy Gannon and Rob Browne both teach Leaving Cert Maths as well, so Junior Cycle is taught with the senior course already in view.
A class for every year
1st Years start from the beginning, 2nd Years build on it, and 3rd Years get a dedicated exam class on top — all in the one membership, no upgrade.
Not just Maths
The same support in all 13 Junior Cycle subjects
Weekly grinds and on-demand lessons for English, Irish, Science, Business Studies, French, Geography, German and 5 more — plus every Leaving Cert subject, all in one membership.
