The arc is a growth curve. Consistent effort, pointed in the right direction, bends into an upward path. That's the shape of how a child grows here.
A small, deliberate space where one student and one teacher think out loud together, week after week, until concepts truly click. Built around math, growing into more. Aligned with US, UK, CBSE, ICSE & IB curricula.
Why we exist
Most online tutoring is a video call with a stranger reading from a script. We believe learning deserves more attention than that. A real teacher, real handwriting, real time spent thinking together.
The classroom
Most online classes are one way. A teacher talks, a child half listens. ClassArc is built the opposite way: the student writes, answers, plays, and thinks out loud. Both of you on one shared canvas, in the same moment. Watch a class come to life below.
Both of you draw and write in the same space, live.
Concepts are worked out by hand, not clicked through slides.
Switch between the board and 3D ArcSpace to make ideas click.
The approach
Always one teacher to one student. No group calls, no rotating tutors, no exceptions, because attention can't be split.
Same teacher every class. They remember where your child got stuck last Tuesday, and pick up exactly there.
Concepts are worked, not watched. Both of you write on the same canvas, draw the same diagram, solve the same problem together.
Interactive number games and challenges built right into class. They show up when they make a concept click, never as filler.
Homework, done right
Anyone can hand out worksheets. What matters is the loop. Assign, submit, review, and most importantly, talk through it together in the next class. That's where mistakes turn into understanding.
A mistake left unexplained is just a habit waiting to form. We close the loop before the next page turns.
Why the loop mattersAfter each class, your child gets homework matched exactly to what was just taught, not generic worksheets.
The student uploads their work right inside ClassArc, a photo or a typed answer. No printing, no scanning hassle.
The teacher checks every submission before the next class, spotting exactly where the child struggled.
The next class opens by walking through the homework. Every mistake explained, every doubt cleared, on the shared whiteboard.
The teacher
"I've spent seven years in classrooms watching kids fall behind because the system moves on without them. ClassArc is what I wish existed."

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. We don't ask for or store any payment details on this website. We don't use trackers, cookies for advertising, or third-party analytics that profile you.
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@classarc.in 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@classarc.in.
