What Makes Our Maths Grinds
Outstanding
It’s teaching through testing
Too many students attend grinds without any evidence of improvement. That’s why every Breakthrough Maths grind has in-class testing. Students identify weaknesses and focus on the topics that improve their results.

FAQs
Our grinds are taught in groups.
The student can see and interact with only with the tutor. Your child can ask questions any time in the chat portal, and the tutor will address them throughout class.
The grinds is held at the same time, with the same tutor, every Monday to Thursday. We offer the flexibility to access any class. Each week we will be teaching two different topics, so your child has a choice in when they want to attend.
Our classes run for about 45 – 60 mins.
They’re students at the end of the day and school is already long enough, so we don’t expect them to focus for more than that length of time.
We’ve been teaching for years now and have dealt with hundreds of kids with learning difficulties. Don’t worry, our tutors are well-equipped to teach children of all learning abilities and levels.
We take our time with them and make sure they get the extra attention that they need.
For €149 per month, your child will have: 4 grinds per week + access to all recordings + access to all supplementary notes and resources.
