Welcome: build 6 real projects in 6 days

Welcome to 6 Projects in 6 Days, the fastest, cleanest way to get your hands dirty with real coding, without a 300-hour bootcamp.

One hour a day. Each day gives you short lessons, a video walkthrough, and one small project you build yourself with HTML, CSS, JavaScript, Git, and AI. No coding experience needed.

Here is a taste of what you will build:

The resume website you build on Day 1
Day 1: a resume website
The link-in-bio page you build on Day 2
Day 2: a link-in-bio page
The BMI calculator you build on Days 3 and 4
Days 3–4: a BMI calculator

Then a quote generator, a quiz app, and a bonus AI-powered personality quiz you publish live on the internet.

Thousands of beginners have started here. The course carries a 4.9 average learner rating, and Sigmaschool has been featured in Vulcan Post. You are not the first beginner to start from zero.

One thing we are not

This is not a vibe coding school. Anyone can paste a prompt into AI and take whatever it spits out, and soon that will be worth exactly what it costs: nothing. We train AI-native builders: people who understand the fundamentals, know what their code is doing, and can direct AI with judgment instead of handing everything off to it. You will use AI all week, as a tutor, never as a ghostwriter. That difference is your career moat.

Two more short pages (the people teaching you, and your 6-day plan), then you are writing code. Or start right now:

Go slow. Go steady. Go deep. That is how you actually learn to code.

This lesson has 1 quiz in the portal, where you tick off each step and get feedback on the code you write. Do this lesson free.

"We started Sigmaschool so no one has to spend years and a fortune on a degree just to land a job they don't love. Ship six real projects this week, that's the spark. Let's turn it into a career."

One thing to know about saving your work

Your lesson progress saves to your Sigmo account automatically, so you can always continue where you stopped.

Your project code lives in your coding workspace (StackBlitz), not inside Sigmo. When a lesson opens StackBlitz, sign in so your projects appear in your StackBlitz dashboard. Later, GitHub becomes the permanent home for the projects you want in your portfolio.

Your 6-day plan

Here is your 6-Day Success Plan, one hour per day:

  • Day 1, Resume website: learn HTML, create links and text, understand how websites read HTML.
  • Day 2, Link in Bio: style with CSS, design buttons, add your profile picture for employers.
  • Day 3, Simple BMI calculator: data types, variables, and showing data.
  • Day 4, Better BMI calculator: user inputs and making the page interactive.
  • Day 5, Random quote generator: lists of data and showing quotes randomly.
  • Day 6, Quiz app: checking whether an answer is right or wrong.
  • Bonus, Personality Quiz + AI: call an AI from your app and publish it live with GitHub Pages.

Use this loop every day:

  1. See the finished project.
  2. Watch the walkthrough once for the map.
  3. Build it yourself, step by step.
  4. Test one input that was not in the example.
  5. Tick a task only after you did it.
  6. Explain one thing you learned.

Sigmo AI is your tutor, not your ghostwriter. Ask for simpler words, a small example, or the next debugging clue. Keep the building in your hands.

That is the whole briefing. Next lesson, you start building your resume website. Let's go. 🚀
