CT Math

Course Overview

A 90 in Grade 10 does not guarantee a 90 in Grade 11.

CT Math is a levelled mathematics program that runs from foundations through to AP and contest mathematics. Students are placed by what they can actually do, then move up level by level.

It is led by practising Ontario teachers, and it is a complement to school mathematics, not a replacement.

Starts the week of November 16, 2026

Monday and Tuesday evenings at 240 Riviera Dr, Unit 1, Markham.

Class times are confirmed after the placement test.

The free placement test decides your child’s level.

When: Monday and Tuesday evenings; senior and AP levels meet on Thursday evening
The year: 30 weeks, in modules of about 10 lessons
Joining later: students can join at the start of any module
Placement: by a free placement test, not by school grade
Class size: small classes, grouped by level

How to Join

The free placement test takes the guesswork out of choosing a level. No booking needed:

Fill in the free placement test form. It takes a few minutes
We email you the test paper for your child’s grade
Your child writes it at home. Reply to that email with the answers and working (photos are fine)
We mark it and send you the placement result, with the current level, the concept gaps and the recommended class

Classes start at the beginning of a module. The first module begins the week of November 16.

Why a 90 Can Become a 60

Marks in Grades 9-10 and marks in Grade 11 measure different things.

Grade 9 math has been de-streamed since 2021 and is designed to include every student
Grades 9-10 questions are short, with one or two steps
Grade 11 brings functions, modelling and multi-step questions with a lot of reading
Ontario teachers judge Knowledge, Thinking, Communication and Application separately, so correct answers alone may not earn the top mark
By the time parents see Grade 11 marks, often at the midterm report, much of the term’s work is already counted

A high mark early on shows a good fit with that design. It does not show readiness for what comes next.

A 90 Gets You in the Door. It Doesn’t Protect You.

Among Ontario applicants entering university, a 90+ average is now the majority.

At U of T, the share of first-year students with a 90+ high-school average rose from 30% in 2014 to 59% in 2024. When almost everyone has a 90, the mark alone says less.

That is why external yardsticks matter. AP exams and math contests use one marking standard for everyone, however a school marks. They are a way to stretch students who are already solid, not a way to patch gaps.

One Early Gap Becomes a Chain

Math builds in a spiral. One weak spot early on makes everything after it wobble.

Research following large samples in the U.S. and U.K. found that fraction and division skills in elementary school predict high-school algebra and overall math achievement five to six years later (Siegler et al., 2012, Psychological Science).

That is why we fix the foundation first, instead of pushing ahead on top of a gap.

Our Approach

Fill the gaps → Build thinking → Then try contests

Fill the gaps. Find what is missing before anything else is added
Build thinking. Understand why a method works, so the student can handle a question that is worded differently and explain the process clearly
Then try contests. Contests are a check-up, not the goal

Nobody starts with a full marathon. Foundations and confidence come first; contests come when the student is ready for them. No blind acceleration and no endless drilling: each student works at the pace that fits.

Grouped by Level, Not by Grade

The placement test decides the starting level. Students can skip ahead, or fill gaps first.

Level	Roughly
Elementary foundations	Grades 3-5
Pre-algebra	Grade 6
Algebra	Grades 7-8
High-school math	Grades 9-10
AP Precalculus · AP Calculus	Grades 11-12

The level-to-grade match is approximate. Placement results take precedence.

Know Where Your Child Stands

Every student takes a free placement test and receives a written report.

Current level, based on actual ability rather than grade
Which concepts have gaps, down to the concept and not just one overall score
What comes next: fill the gaps, follow the main track, or take on a challenge

Parents See More Than a Mark

Progress is tracked concept by concept. When a student gets something wrong, we trace it back to the concept that is actually missing and fix that first. Parents can see which concepts are secure and which still need work, instead of waiting for a single mark.

Prevention Is the Cheapest Insurance

Finding out in Grade 10 whether a child is ready costs far less than repairing a 60 in Grade 11, once that mark is on the record universities see.

A placement test, or one contest written “cold” in Grade 10 with no special preparation, shows early where the gaps are, while there is still time to close them.
