Dedicated Success Coach
King's Interhigh offers live lessons in 3 regional timetables — but you still have to show up at a fixed time. Inventum gives you three entirely different learning approaches, from fully asynchronous to live. You only pay for the level of support your child actually needs.
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
Expert recorded lessons you can pause, rewind, and re-watch until mastery is achieved. World-class instruction without any rigid scheduling — study when you are most focused.
Ideal for: Students who need structure but cannot commit to fixed time slots
Small-group live sessions that are intimate and discussion-based — not passive digital lectures with dozens of silent students. Real-time engagement without the lecture-hall experience.
Ideal for: Students who thrive on real-time interaction and collaborative problem-solving

Get an academic assessment, ask your questions, and leave with a clear online school plan before you make an enrolment decision.
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.
You can complete the application form on our website by clicking the “Apply” button.
Once we receive your application, we will contact you within 48 hours to arrange an onboarding call. During this call, you will be introduced to all our platforms, handbooks, and practices and assigned a dedicated study coach. After this, you are ready to start!
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.
