Here you will find free, downloadable, chapter-wise Biology practice questions for both 1st and 2nd PUC, designed for students preparing for PUC board exams, NEET, and KCET. Each set focuses on a single chapter or a tightly bundled group of related topics, so you can work through exactly the area you need without wading through the whole syllabus at once. Browse by 1st PUC or 2nd PUC below.

Why Chapter-Wise Practice Matters

Biology builds on itself in ways that are easy to underestimate. Genetics, Molecular Biology, and Evolution lean directly on each other, and Ecology’s chapters share overlapping terminology that’s genuinely easy to mix up without focused, chapter-by-chapter practice. Working through one topic at a time surfaces exactly where your understanding is shaky, before it turns into confused answers across several related chapters at once. 

This matters even more for entrance exams: nearly 90% of KCET and NEET Biology overlaps directly with the 2nd PUC syllabus, so time spent mastering a chapter here carries real weight well beyond your board exam. See the II PUC Biology Syllabus and NEET Biology Syllabus to see this overlap clearly.

Once you have worked through the chapters that apply to you, the natural next step is the mixed-practice sets that combine related chapters, and from there a full-length mock test on the NEET mock test hub or KCET mock test hub to see how it all holds together under real exam conditions. 

1st PUC Biology: Bridge-Course Mixed Practice

1st PUC Biology is covered as two mixed-practice papers, each bundling several high-yield topics together rather than one chapter per set. Treat these as broad revision material for the foundational concepts that carry into 2nd PUC and your entrance prep. See the I PUC Biology Syllabus for the full chapter list before you begin.

2nd PUC Biology: Chapter-Wise Practice

Complete chapter-wise coverage of 2nd PUC Biology across all 13 official chapters in these 12 practice sets (Organisms, Populations and Ecosystem share one combined file, since the source material interleaves both topics throughout). Refer to the II PUC Biology Syllabus for the exam pattern and marks distribution before you begin.

Mixed / Combined Practice Sets

Once you’ve completed the related chapters above, attempt these combined sets to practise moving between topics the way you will in an actual exam.

How to Use These Materials

For the most effective prep, work through these materials in sequence rather than jumping straight to mock tests. Check the II PUC Biology Syllabus page first if you want the structural overview and exam pattern before you dive in.

  1. Read the chapter synopsis first.
  2. Attempt the chapter-wise practice set (or bridge-course paper for 1st PUC).
  3. Attempt the related mixed-practice set where one exists.
  4. Move on to a full-length. Use the NEET mock test hub or KCET mock test hub 

This page is a step in that sequence, not a replacement for either your syllabus review or a full mock test closer to exam day. Explore related study materials for Physics, Chemistry, and Mathematics, or reach out to Giraffe Learning if you would like guided support working through these chapters.
