WAJD Skills: AI and Robotics

WAJD Skills teaches how artificial intelligence and robotics actually work, by having you build them. Every idea arrives with runnable Python you can read, copy and change. There is no account, no advert and no price, and your progress stays on your own device.

HOW EACH UNIT WORKS
Every unit runs the same four steps. Learn it, a plain explanation with worked examples and real code. Practise it, retrieval questions with instant feedback that tells you why. Build it, one genuine task with a checklist and starter code. Prove it, a mastery check you can retake as often as you like.

24 TRACKS, 77 UNITS
Neural networks and CNNs. Inside a large language model. Transformers in depth. Reinforcement learning. Generative AI. Bayesian thinking and uncertainty. Physical AI and robotics. Soft and gel robotics. AI safety and honest evaluation. Computer vision from pixels up. Optimisation and evolution. How AI agents work. Classic machine learning. Probability by simulation. Statistics that hold up. Networks, from friends to PageRank. Signals, sampling and frequency. Edge AI on small devices. Cryptography. Databases and SQL. Quantum computing in NumPy. Alongside those sit AI literacy and prompting, coding foundations, and data and spreadsheets, for anyone starting from nothing.

REAL PYTHON, NOT PSEUDOCODE
235 code snippets across the library, written in NumPy and the Python standard library, every one executed and its printed output checked before it shipped. Read the code, tap Copy, and run it wherever you write Python.

MASTERY, NOT MEMORISING
The mastery check draws ten questions from a pool, so no two attempts are the same, and you need nine right to pass. Options are written so that guessing the longest answer does not work. If you do not pass, the check reopens after a short gap, because a spaced second attempt teaches more than an immediate one.

A FREE CERTIFICATE
Finish every unit in a track at mastery and your certificate is issued automatically, ready to print. It is an honest record of what you did on WAJD Skills. We do not claim it is a regulated qualification and it is not accredited by an awarding body.

WHO IT IS FOR
Two kinds of learner. Students of 14 to 16 who want the real mechanism rather than a summary, and post 16 students and adults retraining towards work in AI, data and robotics. The AI and robotics core assumes you can follow Python. Coding foundations starts from nothing.

FREE AND PRIVATE
No account and no sign in. No adverts. No tracking and no profiling. No camera and no attention monitoring. No messaging, so no contact from strangers. Your progress and your certificate live in your browser storage on your own device, so there is nothing about you for us to hold, and clearing your site data clears all of it.
