After reading a chapter from the PDF, solve 50+ MCQs from Lucent Biology or Kiran’s SSC Biology. Note: Khan Sir’s PDF must be complemented with MCQ books—it is not a question bank. A: No
Take a previous year paper (SSC CGL 2022). Mark every biology question. Open the Khan Sir Biology PDF and find the exact page where that concept is explained. If it’s missing, add a margin note from NCERT. This creates a customized hybrid book.
If you cannot find a reliable Khan Sir PDF, these alternatives are equally good for competitive exams:
A: No. UPSC requires deeper understanding of environment and ecology. Use it for basic biology (e.g., hormones, vitamins) but supplement with Shankar IAS Environment or NCERT.
This is a grey area. Khan Sir’s team officially provides paid PDFs and physical notebooks through their Khan GS Research Centre app and website. However, thousands of third-party websites illegally upload scanned copies of these notes.
What Khan Sir has said publicly: In several videos, he has expressed that education should be free, but pirated PDFs hurt his ability to maintain quality and pay staff. He encourages students to use his official YouTube channel (free video lectures) and buy the PDF only if affordable.
Our advice: If you have the means, purchase the official PDF (₹150–₹300). If not, use free versions but consider donating or subscribing to his channel. Never pay random websites for a "Khan Sir Biology PDF" — most are scams containing viruses or old content.
