Frequently asked questions

Is this course really free?

Yes — 100% free. No signup, no credit card, no email required. All lessons, quizzes, and certificate of completion are free forever.

Do I need to install anything?

No. The entire course runs in your browser on phone, tablet, or laptop. No downloads, no accounts.

How long does the course take?

About 10 minutes per lesson. One lesson per day takes about 1-2 months total. Many learners finish in 2-3 weeks by doing multiple lessons per sitting.

Will I get a certificate?

Yes. After completing all lessons, generate a personalized certificate with your name and share it on LinkedIn. Not accredited, but signals commitment to recruiters.

Do I need prior experience?

No. Every course is designed for complete beginners. Each lesson starts with a plain-English analogy before any technical concepts.

How is this different from YouTube tutorials?

Three things: interactive — quizzes and hands-on challenges after every lesson; structured — a deliberate learning path, not random videos; gamified — XP, streaks, spaced repetition so knowledge actually sticks.
