How a term runs.
The same rhythm for every program, so you always know what happened this week and what comes next.
-
Week 0
Free assessment
Forty minutes with a tutor to find the gap, not just the grade.
-
Week 1
A written plan
What we will teach, in what order, and what good looks like by the end of term.
-
Every week
The same tutor
Sessions at the same time with the same teacher, and one line for you afterwards.
-
Every 4 weeks
A short report
Marks, effort and the next step, written by the tutor and sent home.
Taught by teachers.
Every tutor holds a teaching credential or a graduate degree in their subject. Your child sees the same one every week.
“If a student can explain the step to me, they own it.”

What families tell us.
Maya used to cry over algebra homework. Eleven weeks in, she asked if she could do the extension sheet.
“The four-week reports were the first time a tutor told us what was actually going wrong.”
“Sam made the SAT feel like a puzzle I could practise, not a judgement.”
Questions parents ask first.
Anything else, call or email. We would rather answer it now than after the first session.
What happens in the free assessment?
Forty minutes with a tutor in the student's weakest subject. You get a written summary of what we found and a recommended plan, with no obligation.
One-to-one or a small group?
Groups of up to four suit most students and cost less. We recommend one-to-one for exam preparation or when confidence is very low.
Do you tutor online?
Yes. Online sessions use a shared whiteboard and the same tutor and plan as in person. Many families mix the two.
Are your tutors qualified teachers?
Every tutor holds a teaching credential or a graduate degree in their subject, and all have current background checks.
What if we need to miss a session?
Give us 24 hours' notice and we will move it within the same fortnight. Late cancellations are charged.
How do you share results?
A short written report every four weeks, and a conversation at the end of each term. Results appear on this site only with a family's permission.
Start with forty minutes and a plan.
The first assessment is free. You leave with a written summary of where your child is and what we would teach first.
