Frequently Asked Questions (FAQs)
Q1. Are these coding websites really free?
Yes, every resource listed here offers high-quality content for free. Some platforms may offer paid upgrades or premium features, but the core learning material — tutorials, projects, and exercises — can be accessed without spending a rupee or dollar.
Q2. I’m a complete beginner. Where should I start?
If you’re just starting out, we recommend:
- W3Schools for HTML/CSS and basic JavaScript
- freeCodeCamp or Codecademy (Free Tier) for structured beginner paths
- CS50 if you want to understand computer science fundamentals early on
Start with one and stick with it consistently — that’s more important than jumping between platforms.
Q3. Can I get a job by learning from free resources?
Absolutely. Many developers have landed full-time roles, freelance gigs, or even launched startups by using free learning platforms. Resources like The Odin Project, freeCodeCamp, GeeksforGeeks, and LeetCode are especially focused on building job-ready skills and portfolios.
Q4. How long will it take to become job-ready?
That depends on your background, learning pace, and dedication. On average:
- Consistent learners (10–15 hours/week) can gain job-ready web dev or DSA skills in 6–9 months
- More intense learners may be ready in 3–5 months
The key is not speed, but daily consistency and building real projects.
Q5. Do these platforms give certificates?
Yes, some do.
- freeCodeCamp offers verified certifications upon completion
- CS50 (via edX) provides a free certificate if you complete the final project
- Google’s ML Crash Course offers a completion badge
Others like W3Schools offer certificates for a fee, but the learning content itself remains free.
Q6. Is internet access enough, or do I need a powerful computer?
Most platforms run in the browser, so a basic laptop with internet access is enough to get started. For example:
- freeCodeCamp, W3Schools, Codecademy, and Google Colab work fully online
- For mobile app or ML development (like Flutter or TensorFlow), you may need more RAM (8GB+) and some setup later on
Q7. I’m not good at math. Can I still learn coding or AI?
Yes. While certain fields like AI and machine learning involve math, many areas like web development, frontend design, and basic scripting don’t require advanced math skills. And when math is needed, platforms like Khan Academy or YouTube can help you fill those gaps for free.
