Legitimate Options:

  1. Durga Software Solutions Official Portal

    • Their "Core Java with OCJP/SCJP" course includes a downloadable PDF. Cost is roughly ₹3,000 - ₹5,000 INR ($35–$60 USD). You also get video access.

  2. Udemy / Other Platforms

    • Durga Sir has authorized some Udemy instructors to resell his material. Check "Course Curriculum" for "Includes downloadable PDF workbook."

  3. College Network / Campus Drive

    • Several engineering colleges have licensing agreements. Ask your placement officer or library if they provide access.

Step 4: Mock Certification Test

Treat the last 100 pages (usually containing SCJP-style objective questions) as a real exam. Time yourself: 60 questions in 90 minutes.

Pro Tip: Keep a separate "Durga Notes.docx" file where you summarize each chapter in your own words. The act of rewriting deepens memory.

Step 3: Interview Question Practice

Each chapter ends with a "Frequently Asked Interview Question" section. Create flashcards from these. Practice explaining concepts like "Can we override a private method?" out loud.
