Questions learners ask
Still unsure? Ask the team on WhatsApp or call +91 93981 39619.
Will real money be charged during the labs?
No. Every payment lab uses Stripe and Razorpay test modes with test cards and test UPI, so no real money moves.
Do I need a registered business for Stripe or Razorpay?
Not for learning — sandbox and test accounts are free. You’ll need business verification only when you go live with a real product, and we explain that process.
Which video platform should I use for my product?
It depends on whether you need scheduled meetings (Zoom, Google Meet, Teams) or video embedded inside your app (Zoom Video SDK, Agora, 100ms, Daily, Jitsi). You’ll build with several and learn how to choose.
Can I integrate WhatsApp without a business account?
WhatsApp Business Cloud API offers a free test number for development. Sending to real customers requires business verification and approved templates, which we walk through.
Is this useful for freelancers?
Very. Payments, video meetings, notifications and sign-in are among the most requested features in client projects.
What laptop or setup do I need?
A laptop with 8 GB RAM. All payment and video labs use free sandbox or developer accounts — no real money moves.
Are classes live or recorded?
Live and interactive, with mentors answering your questions in the session. Every session is also recorded so you can revise or catch up.
When are the classes?
Live online · weekday evenings or weekends. Exact timings are shared before each batch starts, and we plan them around working hours and college schedules.
What if I miss a class?
Watch the recording, finish the lab, and bring questions to the next doubt session or the mentor group. Falling behind is normal — just tell your mentor early.
Which language are classes taught in?
Simple, clear English. If you’d like help in Hindi during doubt sessions, ask us when you enrol.
How big is a batch?
We keep batches small so mentors can review everyone’s code. Ask us for the current batch size.
How do I get my doubts solved?
Ask in the live session, post in the private mentor group, or bring it to the weekly doubt-clearing session. Mentors also comment directly on your GitHub pull requests.
How do I earn the certificate?
Complete the hands-on labs and the capstone or final project. Your mentor reviews and signs it off, and your certificate is issued with a unique ID listed on our public verification page.
Is the certificate recognised?
It’s issued by Ezibell Tech, a Government of India–registered company (MSME/Udyam and GST registered), and carries a unique ID that anyone can verify online. It’s a professional training certificate — not a university degree or a government accreditation — and its real value comes from the projects you build and the mentors who can vouch for your work.
Do I keep access to the recordings and materials?
Yes, recordings and materials stay available after the programme ends. Ask us for the exact access period for your batch.
Do I own the projects I build?
Yes. Everything lives in your own GitHub account and is yours to show employers.
What are the fees? Is EMI available?
Fees depend on the programme and batch. Message us on WhatsApp or call, and we’ll share the current fee, instalment options and any student or early-bird discount within a few hours.
What is the refund and batch-transfer policy?
Refund and batch-transfer terms are shared in writing before you pay, so you know exactly where you stand.
Do you guarantee a job or placement?
No — and be careful of anyone who does. We give you real skills, a portfolio, interview practice and introductions within our network.
Can I talk to a mentor before enrolling?
Yes. Book a free counselling call on WhatsApp or phone. We’ll look at your background and recommend the right programme — honestly, even if it’s a different one.
