Your mentor

Working developer · 5+ years of real, live-project experience

Your sessions are taught by a working developer with 5+ years of real, live-project experience — someone who writes and ships production code every day, not a content creator.

We teach concepts and review your code. We never write or complete graded assignments or exams. Read our policies.

Questions, answered

Do I need any experience before this batch?

Prerequisite: Java basics (Java Foundations or a CS1/CS2 course in Java).

How much time does it take each week?

Two live classes of 75 minutes, plus a few practice questions and one code review on your own code — about 3–4 hours a week.

What if I miss a class?

Every class is recorded and shared within 24 hours, so you can catch up and still ask questions in the doubt channel.

How do payments and refunds work?

You reserve for free and only pay by secure link once your batch is confirmed. Full refund before the third class — see our policies.

Can I get 1:1 help instead?
