Rafi was the kid stuck on YouTube and games. Three months in Junior Coders and he started building his own game instead of just playing them. His teacher really knows what makes him tick.

What parents say
Rafi was the kid stuck on YouTube and games. Three months in Junior Coders and he started building his own game instead of just playing them. His teacher really knows what makes him tick.

I am a software engineer myself. I was skeptical about online classes for a 7-year-old. The methodology is solid, they really do teach computational thinking, not just drag-and-drop.

My daughter was stuck on multiplication for a year. After the AI diagnostic we found a gap from grade 1 we had no idea about. Six weeks of weekly lessons closed it, and now she is ahead in school maths.

Before you pay
We are not asking for blind trust. Here are three things you can do before any money changes hands.
Take the free trial class
The 60-minute class happens before any payment. Your child joins a live online class with a real teacher, not a recorded video, and you see how the teaching works.
See who does the teaching
The teaching team page lists Algonova Indonesia teachers with names, photos and the subjects they teach. Our teachers mentored 2025 Python Olympiad medalists.

No risk
Four steps, all of them before any buying decision.
01
Pick a time
You choose the day and hour that suits your family. No card details and no payment.
02
Your child takes the 60-minute class
A live online class with a certified teacher in a small group of up to 10 students. Your child finishes a first project in that same class.
03
Talk to the team
After the class the team calls you and says which learning track fits your child, including when the answer is not yet.
04
Decide without pressure
Some families enrol two months later, once the school timetable allows. That is fine.

Algonova is an international online school operating in 97 countries, and classes for Indonesian families are run by the Algonova Indonesia team in Bahasa Indonesia. Because all classes are online, teacher and student do not need to be in the same city: a child in Jakarta, Surabaya or Denpasar takes exactly the same programme. The company's legal details, address and official contact information for Indonesia sit at the bottom of every page on this site, including this one. Algonova has taught since 2016 and has more than 1,000,000 graduates across 97 countries, with an average parent rating of 4.9 out of 5, and is a Bett MEA Awards winner.

No. Algonova Indonesia teaches fully online, so there is no branch or physical classroom in Bandung, Surabaya, Semarang, Malang, Medan, Denpasar or any other city. Your child joins live classes from home through a browser, and all that is needed is an ordinary laptop or computer with a stable internet connection. What this means for parents: no travel time and no travel cost, schedules chosen around your child's other activities, and the same teachers and curriculum for families in any city. So if you are looking for the nearest Algonova, the answer is that the same classes are available anywhere in Indonesia at the same price, from Rp 102,000 per lesson. The free trial class also runs online, so you can judge the teaching quality without leaving home and without paying first.
Algonova Indonesia costs from Rp 102,000 per lesson. That figure applies to the Group format of 6 to 10 children. The Mini format of 2 to 4 children and Private one to one lessons cost more per lesson. The price covers the live class with a certified teacher, access to the learning platform, and a certificate each time your child completes a level. Three things set the final number: the programme chosen, the class format, and the number of lessons per month. A lesson runs 45, 60 or 90 minutes depending on the programme and the child's age. The team gives you the final figure for your child's schedule after the free trial class, before any payment and with no obligation to enrol. There is no separate registration fee and no card details are requested for the trial. If you find a different figure on another site, the price on the official Algonova Indonesia page is the one that applies.
The reviews on this page come from Algonova Indonesia parents and each one is attributed rather than posted anonymously. The same reviews also appear on the programme pages those children attend, for example the coding courses page and the mathematics classes page, so you can read them in context instead of only on a page built to display reviews. Reviews that mention the hard parts are deliberately not removed, because a page of pure praise is useless to a parent. Algonova ratings circulating on third party sites are not always collected from Algonova families, so treat this page and the programme pages as the primary source. The strongest check is still first hand: the free trial class happens before any payment, so you can judge an Algonova teacher working with your own child.
That is why the trial class comes before any payment: you see how the teacher works and how your child reacts first, then decide. If the answer after the free trial is not yet, nobody pushes. Nothing is charged and no card details are stored, so deciding not to continue costs you nothing. If your child has already started and needs a different level, a different teacher or another time slot, the Algonova team can rearrange it without restarting the programme. Children move between levels as their ability develops rather than being locked into the level they first joined. Cancellation terms for an active enrolment are set out in the Terms and Conditions linked at the bottom of this page, and the team will confirm them to you in writing before you enrol.
Use the free class button on this page, pick a time that suits your family, and your child joins a live online class with a certified Algonova teacher: a 60 minute masterclass for coding, or a 45 minute diagnostic for mathematics. You pay nothing for this class and you do not need to enter card details. Afterwards the team calls you to explain which learning track fits, based on what the teacher saw in the class, and gives you the exact price for that schedule, from Rp 102,000 per lesson. There is no obligation to enrol at that point. If you would rather read other families' experiences first, more reviews sit on the coding courses, mathematics classes and masterclass pages of this site.
