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.

Do I need any experience before this batch?

Prerequisite: Java basics.

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.
