1. Read the plain-English idea
Short explanations define each term the first time it appears. No jargon walls.

Start here.
You do not need a computer science degree, a paid bootcamp or a perfect memory. You need a small, ordered plan and the habit of finishing one lesson at a time.
How a lesson works
Read, try, check, prove.
Every lesson uses the same four steps. You always know what to do next, and you never need to guess whether you understood it.
2. Run or read a real example
SQL and Python examples open in a lab. Other examples are small enough to retype.
3. Answer the knowledge check
A missed question comes back later in the review queue, so it is not lost.
4. Finish the challenge
Write code yourself. The hint and solution are there when you are genuinely stuck.
A six-week starting plan
One clear track, not twenty tabs.
Two to three hours a week is enough to build momentum. Adjust the pace, keep the order.
Learn how pages are built
HTML for structure. Finish the first six lessons and build one page you can open in a browser.
Make it look right
CSS for spacing, colour and layout. Rebuild the same page with a navigation bar and a card grid.
Add behaviour
JavaScript variables, conditions and loops. Make one button change something on the page.
Learn a second language
Python for clear, readable programs. Write small functions and handle input without crashing.
Work with data
SQL SELECT, filters and joins. Ask questions of a real table instead of guessing.
Ship and prove it
Git to save your work, then revise with quizzes and take one certification exam.
Certificates are meant to mean something
Easy to learn. Hard to fake.
Lessons are deliberately patient: examples, steps, common mistakes and a second try. The certification exam is not. It is closed book, timed, scored on the server and covers every lesson in the course.
CoverageOne question per lesson, across the whole course
TimedClosed book, no notes, server-scored
Pass mark80% — knowing the ideas is not enough
AttemptsThree attempts, with a public verifiable credential on a pass
