Pearson Edexcel from Grade 1 to Year 13: 24 subjects across iPrimary, iLowerSecondary, International GCSE and International A Level, each with the units of its scheme of work, a tutor anchored to the specification, the science practicals in a 3D lab, and a Practice Buddy for the past papers you bring. For schools, for homeschooling families, on the phone you already have.

Each has its own page with the units it covers and the tutor who teaches it.
Each subject has a tutor anchored to its Pearson Edexcel specification. Ask by voice or text at any hour; the answer is taught from the specification and worked on a board you can read back.
Upload the past paper or mark scheme you have and the buddy takes you through it question by question, marks your answers and explains what the examiner wanted. No paper to hand? It sets questions from the specification instead.
Every explanation is written out on an interactive board as it is spoken: the equation, the diagram, the essay plan. Read it back, copy it into your notes, ask for it another way.
Biology (A-Level), Chemistry (A-Level), IGCSE Biology, IGCSE Chemistry, IGCSE Physics, Physics (A-Level), Science: practical work on a 3D bench, marked on the server, repeatable until the method is yours.
A tutor per subject, assignments, a parent dashboard and a teacher when you want one. Homeschooled learners sit the exams as private candidates at a Pearson centre.
iPrimary and iLowerSecondary before International GCSE, International A Level after it, with the record following the learner up.
Because the internet does not know which specification you sit. Every tutor and buddy on CognitaSTEM is anchored to the Pearson Edexcel specification and to the files you upload, and to nothing else: your syllabus and your files are the only truth they teach from.
Biology (A-Level), Business (A-Level), Chemistry (A-Level), Computer Science (A-Level), Computing, Economics (A-Level), English, Global Perspectives, IGCSE Biology, IGCSE Business Studies, IGCSE Chemistry, IGCSE Computer Science, IGCSE Economics, IGCSE English Language, IGCSE Geography, IGCSE History, IGCSE Mathematics, IGCSE Physics, Law (A-Level), Mathematics, Mathematics (A-Level), Physics (A-Level), Psychology (A-Level), Science. Each has a page listing its units.
Grade 1 to 6 (iPrimary), Grade 7 to 9 (iLowerSecondary), Year 10 and 11 (International GCSE) and Year 12 and 13 (International AS and A2 Level).
From the Pearson Edexcel specification and the files you upload, and nothing else. The tutors and buddies are grounded in the units listed on these pages and in the past papers, notes and mark schemes you give them; they do not invent facts or pull from the open internet. Your syllabus and your files are the only truth they teach from.
A free account gives you the tutors with a daily allowance, the 3D labs and the Practice Buddies. Premium adds unlimited tutor time; the pricing page has the current price in Kenyan shillings, and schools and homeschooling families pay the same.
Yes. Everything runs in the browser on an ordinary smartphone over mobile data, including the 3D labs.
No. Pearson Edexcel exams are sat at a registered Pearson centre; homeschooled learners enter as private candidates. CognitaSTEM teaches and revises the specification and tells you where a learner stands before the exam.
