Explore the projects See where subjects overlapHow every lesson works
Watch. Practise. Play. Know you’re ready.
The same four steps in every lesson, so students always know what to do next.
1
Watch a narrated explainer
Short scene-by-scene videos that explain each objective with worked examples and diagrams. Students can listen or read the captions, and replay any scene.
- 1,400+ narrated scenes
- Key notes to copy after every video
- 3D models and simulations in many lessons
2
Practise the way CSEC asks
Paper 1 multiple choice and Paper 2 structured questions on every lesson, modelled on real CSEC questions, with instant feedback and model answers.
- Modelled on or adapted from past papers
- Self-marking with the mark scheme
- A timed Paper 1 mock in every subject
3
Play to remember it
Lessons finish with quick games — sort it, sequence it, match it, Myth or Fact — and each subject has an arcade of favourites like Snakes & Ladders, Word Lab and Snake, all powered by the syllabus.
- 766 lesson games + 6 arcades
- XP, levels and badges
- Seven themed skins to choose from
4
See exactly what to revise next
The readiness tracker turns videos watched and practice scores into a percentage for each paper and section, weighted like the real exam — and names the next lesson to study.
- Paper 1, Paper 2 and SBA readiness
- “Revisit these” weak-spot list
- Progress code to switch devices

Made by a teacher
Built by a Trinidad & Tobago secondary teacher with 18 years in the classroom, following the CXC syllabus objective by objective.
No accounts, no ads
Students open a lesson and start. There is nothing to sign up for and no advertising.
Progress you can see
Ask your child to show you their readiness tracker. A progress code lets them move to another device or share it with a tutor.
Works on any device
Phones, tablets, laptops and school computers — any modern browser. Narration uses the device’s own voice, so no big video downloads.
Ready for the classroom
Teachers can project any lesson, use the games as starters, and set the practice as homework. Ask us about class use.
Exam-focused
Practice is modelled on real CSEC Paper 1, Paper 2 and Paper 032 questions, with SBA and practical lessons in every science.

Built in a Caribbean classroom
EduTech STEM Academy was started by Danual Bridgemohan, a secondary school teacher in Trinidad & Tobago with 18 years’ experience teaching Computer Science and Information Technology and running IT and robotics clubs.
The aim is simple: every CSEC student should have clear lessons, real exam practice and honest feedback on how ready they are — wherever they live and whatever school they attend.

Questions
Frequently asked
Is it really free?
Yes. Every CSEC lesson, practice question, game and mock on the site is free to use. Live classes and printed study guides are separate — email us for details.
Do I need an account?
No. Open any subject and start. Your progress is saved in your browser on that device.
How do I keep my progress on another device?
On a library’s main page, press “Copy my progress code”, then “Load a progress code” on the other device.
Does it follow the CSEC syllabus?
Yes. Each course is built objective by objective from the current CXC syllabus, and practice questions are modelled on, or adapted from, CSEC past papers.
Can teachers use it in class?
Yes — project a lesson, play the games as a starter, or set the practice for homework. Email us if you would like to use it with a whole class.
