Still Got Questions? We Got You

If you're thinking it, someone already asked it and we've answered it here.

How do RexX certifications help me get internships?

RexX projects are real-world challenges that mirror industry work. When you showcase them:

Employers see your GitHub repo — proof you built it
Certificates are verifiable via public link
Projects span full-stack, data science, and GenAI

Want to stand out? Browse projects and pick one that matches your target role.

What's the difference between RexX and free online courses?

Free courses teach concepts. RexX gives you verifiable proof you applied them. You build a real project, push to GitHub, and earn a certificate that anyone can verify. No video lectures — just specs, constraints, and automated review.

Do employers recognize RexX certificates?

Yes. Certificates link to your public GitHub repo, so recruiters can see your actual code. We use cryptographic verification — the same approach used by professional credentials. Learn how verification works.

How much does a RexX project certification cost?

Projects start at ₹99. Each project is a one-time payment — no subscriptions. You pay once, build at your pace, and keep the certificate forever.

Is there a refund if I don't complete a project?

We don't offer refunds after purchase, but you can try before you buy: every project has a free preview of specs and requirements. Only pay when you're ready to submit for certification.

How long does it take to complete a project?

Depends on the project and your experience. Most students finish in 1–3 weeks. Each project lists an estimated duration (e.g. "2–4 weeks"). Build at your own pace — there's no deadline.

Can I use my own GitHub repo or do I need to start from scratch?

You can use an existing repo if it meets the project specs. Most students start fresh to follow our structure. Either way, you link your repo when submitting — we verify the code and issue the certificate.

What if I get stuck on a project?

Each project includes detailed specs and constraints. For deeper help, check our blog and community. Many projects have hints in the documentation. Stuck? Pick a simpler project first and level up.

Do I need to know Git before starting?

Basic Git is enough: clone, commit, push. If you're new, we recommend a quick tutorial (e.g. GitHub's "Hello World"). You'll need a GitHub account to submit and receive your certificate.
