One-to-one CBSE and ICSE maths from $13.50 a class, following the NCERT and ICSE sequences your child's school actually uses — taught by the same teacher every week, in our own classroom software.
Why this matters
Most international platforms teach a Western curriculum and treat CBSE or ICSE as a variation of it. They are not. The chapter order differs, the exam style differs, and ICSE goes deeper on several topics than CBSE at the same class level.
Our teachers are in India and teach these boards as their primary curriculum. If your child is in Class 9 ICSE, the class follows the Class 9 ICSE sequence, chapter by chapter, in the order the school teaches it.
Class 1 to Class 12, following the NCERT sequence for CBSE and the council syllabus for ICSE.
What sets this apart
CBSE and ICSE are different curricula, not the same content relabelled. We teach whichever your child sits, in that board's order.
Families in the UK, US, Canada and the Gulf study the Indian syllabus properly — which matters if your child returns to school in India or sits board exams.
Previous years' papers and question patterns layered onto proper syllabus teaching, rather than replacing it with drill.
How a class runs
The first class is a diagnostic. A Class 8 student struggling with algebra usually has a Class 6 fractions gap underneath, and teaching Class 8 harder will not fix it.
Marks come from method. A teacher who only sees the final answer is guessing at what went wrong.
Why we watch the workingThe teacher opens last class's work and last week's homework. No re-explaining, no lost time.
Teacher and student write on the same interactive worksheet, live. The working appears as it is thought, not after.
Your child works a problem unaided while the teacher watches the method form and steps in only where it goes wrong.
Set from exactly what was taught, reviewed together next class. That review is where the learning actually lands.
Coverage
We follow the NCERT textbook sequence for CBSE and the council syllabus for ICSE, and prepare for board exams where relevant.
The platform
Most online tuition is a video call plus a shared PDF. ClassArc built its own classroom instead, because a maths lesson needs more than two faces on a screen.
Teacher and student open the same interactive worksheet and both write on it live. There is a shared whiteboard for working a sum through together, and answers sync as they are typed, so the teacher watches the method rather than just the answer.
Your child joins from a browser. Nothing to install.
A sum marked wrong teaches nothing. A method corrected as it is written teaches everything.
Why we built our ownPrices in US dollars. Every class is 55 minutes, one-to-one, with the same teacher. First class free, no card required.

When you book a demo or sign up for classes, we collect your name, your child's name, email, WhatsApp number, time zone, and the grade you're inquiring about. That's it.

Only to schedule and run your classes, send you class reminders, share homework and progress, and answer your questions. We'll reach out by email or WhatsApp, depending on what you tell us works better for you.
Your teacher, and the small team supporting them at ClassArc. We never sell, rent, or share your information with anyone outside ClassArc. We use Formspree to receive form submissions, and standard email and WhatsApp for messaging, nothing else.
We treat any information about your child with extra care. We only collect what we need to teach them well, such as their grade and what they're working on. We never use a child's photo, name, or work in any marketing without the parent's explicit written permission.
You can ask us to show you what we have on file, correct anything inaccurate, or delete your data entirely, at any time. Just email hello@theclassarc.com and we'll handle it within a few days.

ClassArc is a one-on-one online tutoring service. We provide live, scheduled classes between a teacher and a student, along with homework, feedback, and study support.
Each class is 55 minutes. You can reschedule or cancel a class up to 5 minutes before it starts. If you miss a class without notice, we usually credit it back to your balance and reschedule based on what works for the teacher and student.
The first demo class is free, no card required. After that, plans are billed in advance for the number of classes you choose (8, 24, or ~48). We'll send you a payment link directly once you've picked a plan.
If you want to stop classes at any point, we refund whatever class balance is left on your plan. No questions asked, no friction. Refunds are processed within 7 business days.
We expect students and parents to treat teachers with respect, and teachers to do the same. We reserve the right to end the relationship if classes become unsafe, abusive, or disruptive, with a full refund of any unused balance.
If we update these terms, we'll email you before the changes take effect, so you have time to review them.
For anything, email hello@theclassarc.com.
