This Free Online Mock Test for NEET Biology is based on the Unit 1 Diversity of Living Organisms of NCERT book. This test has covered questions from Chapter 1: The Living World and Chapter 2: Biological Classifications. This test will assess your understanding of:

• Chapter 1: The Living World
  • What defines a living organism
  • The vast diversity within the living world
  • Systems for classifying organisms (taxonomy)
  • Tools and resources for classification
• Chapter 2: Biological Classification
  • The Five Kingdoms (Monera, Protista, Fungi, Plantae, Animalia)
  • Unique characteristics of viruses, viroids, and lichens
  • How classification systems have changed over time

This mock test features questions directly inspired by those found in previous years’ NEET and other national-level exams. It comprehensively covers all essential topics from both chapters. Simply access this free resource, put your knowledge to the test, and evaluate your current understanding.
