Which Online School Actually Teaches Your Child?

Both offer Cambridge iGCSEs and A-Levels online. But Nisai is built around specialist SEND and UK alternative provision — while Inventum delivers expert teaching to any learner, with 1-on-1 teacher sessions & 1-on-1 support included, at a fraction of the cost.

How it works

How Inventum Works

Nisai teaches exclusively through fixed live sessions with cameras deactivated — one model for all students. Inventum gives you three genuinely different learning journeys, from fully asynchronous to live small-group. You choose the level of structure and interaction your child actually needs.

Journey 1

Fully Asynchronous Learning

24/7 access to our premium core curriculum materials. Study entirely at your own pace, free from any bell schedule or forced live attendance. Perfect for highly independent learners.

Ideal for: Independent learners, professional athletes, globally mobile families

Journey 2

Recorded Precision Teaching

Expert recorded lessons you can pause, rewind, and re-watch until mastery is achieved. Actual teaching — not a fixed timetable slot you must attend or lose entirely.

Ideal for: Students who need structure but cannot commit to fixed live sessions

Journey 3

Live Precision Teaching

Small-group live sessions that are intimate and discussion-based. Real-time interaction with your subject teacher — without the rigid timetable of a fixed institutional schedule.

Ideal for: Students who thrive on real-time interaction and collaborative problem-solving

The Real Cost Comparison

Nisai's private tuition is published in SGD and JPY, reflecting their Asia-Pacific market — equivalent to approximately £1,575 per iGCSE subject and £1,715 per A-Level subject per year at current exchange rates. That is before a registration fee and before families arrange and pay for their own exam centre. Inventum's pricing is Euro-denominated, transparent, and covers what it says it covers.

Which School Is Right for You?

The Honest Answer

Nisai might suit you if...

  • Your child has an EHCP or complex SEN and your local authority is funding the placement through commissioned alternative provision
  • Your child is a school refuser in acute need and requires Nisai's short-term 10-week rolling provision to re-engage with education
  • Your child has severe anxiety and benefits specifically from the deactivated-webcam, short-lesson, low-pressure model Nisai is built around
  • You need a DfE Section 41 approved provider to satisfy the legal requirements of an Education, Health and Care Plan

Inventum is built for you if...

  • You are a private-paying family who wants expert teaching — not just a seat in a group class — at a price that is transparent from the start
  • You want 1-on-1 sessions with a subject teacher included, not just group attendance with cameras off
  • You need genuine scheduling freedom: fully async, recorded, or live — adapting to your child's needs week by week
  • You want a richer curriculum including Future Tech and Personal Mindset alongside Cambridge qualifications — not a model that failed Ofsted's standards for PE and creative arts

Frequently Asked Questions.

All the tests and exams in the Upper Primary (Year 5 & Year 6) and Lower Secondary (Year 7-Year 9) are internal Inventum exams taken online. For the second year of the IGCSE program (Year 11), AS (Year 12), and A-Levels (Year 13), the exams have to be taken in a physical Cambridge or Pearson exam centre. You can find the list of exam centres worldwide here.

For the Upper Primary (Year 5 & Year 6) and Lower Secondary (Year 7-Year 9), you will receive a certificate from Inventum when you complete a year level. Cambridge issues your certificate for IGCSE. For AS and A-Levels, your certificate comes from Cambridge or Pearson, depending on which board's syllabus you follow.

Successful completion of A-Levels will give you access to universities around the world. This is the most recognised secondary school certificate globally by universities and employers.

In principle, this is possible, but it will require your time and dedication. You will still pay the fees for two years, as you will have access to 121 teaching, live lessons, etc., for both years.

You decide on the study schedule based on your preferences and timetable. Your dedicated study coach can help you make a schedule that suits your circumstances. When choosing Journey 3, you also commit to the live lessons schedule.

We use precision teaching, meaning the live lessons cover only the critical and most difficult parts of the curriculum. On average, there are two live lessons a week per subject.

This will depend on yourself, the number of chosen subjects and the year level, but on average, a full-time Learner spends approximately four hours a day studying.

The Upper Primary (Year 5 & Year 6) and Lower Secondary (Year 7- Year 9) have five mandatory subjects: English, Maths, Science, History and Geography. There are no mandatory subjects for IGCSE (Years 10&11) and A-Level programs (Years 12&13), but you choose them based on your interests and future plans.

For the Upper Primary (Year 5 & Year 6), Lower Secondary (Year 7-Year 9), and IGCSEs (Years 10&11), you will be required, as a full-time student, to take a minimum of five subjects and for the A-Level program (Years 12&13) a minimum of three subjects.

We are a non-selective school and will therefore not require a certain grade average, but we will assess every case individually. Learners need, however, to be fluent in English as this is the language of instruction.

We look at the Learner’s age and previous schooling history to determine the best starting point for them at Inventum. If there are any doubts, we recommend the Learner take a CAT4 test.

Our high flexibility learning model, combined with the level of support Learners can choose from, is a unique feature among online schools. Together with the Learner, we build the learning journey that caters to their individual needs. By following our mindset modules, we ensure they are ready for the future by educating them on emerging technologies and ensuring they grow as individuals.

Cambridge certificate is recognised globally by universities. We do not, however, have agreements with local educational authorities, so it is the parent’s responsibility to check the rules and possible restrictions for homeschooling or online schooling in their home country.

A-Levels ask students to specialise in three or four subjects in depth, while the IB requires six subjects across a broad range plus an extended essay and Theory of Knowledge. Both are recognised for university entry worldwide.
