Pearson Edexcel English for iPrimary (Grade 1 to Grade 6) and iLowerSecondary (Grade 7 to Grade 9): 4 units of the scheme of work, a tutor, Mr. Daniel Okafor, anchored to them, exam-style questions marked with the reasons, and a Practice Buddy for the past papers you bring.

The 4 units the Pearson Edexcel English scheme on CognitaSTEM follows, in teaching order. Each unit is what the tutor teaches from and what the exam-style questions are set on.
A subject tutor anchored to the Pearson Edexcel English specification. Ask by voice or text at any hour; the answer is taught from the units below 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.
English runs through iPrimary (Grade 1 to Grade 6) and iLowerSecondary (Grade 7 to Grade 9). A learner picks up in whichever year they are in, and the tutor keeps to that year's part of the specification unless asked to look ahead or back.
Homeschooling? The same tutor, labs and buddies work for a child learning at home; a parent sees every session from the parent dashboard.
All 4 listed above, from "Speaking and listening" to "Spelling, punctuation and grammar", following the Pearson Edexcel specification for iPrimary (Grade 1 to Grade 6) and iLowerSecondary (Grade 7 to Grade 9).
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.
