How a custom NEET biology quiz helps

Working through a biology quiz NEET 2025 set built from your own syllabus notes shows you where your recall is weak before the exam does. Generic question banks cover topics your teacher may not have taught, so the time you spend on them is hard to use well.

Questions stay tied to the chapters in your own NEET 2025 biology material.
Explanations show why the correct answer is right and the others are wrong.
Multiple-choice, true/false and open questions test recall at different depths.
Free plan includes 3 generations per month with study in the browser.

Example NEET 2025 biology practice questions

In eukaryotic cells, where does the Krebs cycle take place?The mitochondrial matrix. Glycolysis happens in the cytoplasm, but the Krebs cycle runs inside the mitochondria.

Which blood group is the universal donor for red blood cells?O negative. It lacks A and B antigens and the Rh D antigen, so it is least likely to trigger an immune reaction.

Which hormone lowers blood glucose levels?Insulin, secreted by the beta cells of the islets of Langerhans. It promotes glucose uptake and glycogen storage in the liver and muscle.

In which phase of mitosis do chromosomes align at the metaphase plate?Metaphase. Spindle fibers attach to kinetochores and line up the chromosomes before anaphase separates the sister chromatids.

Which plant tissue carries water and minerals upward from the roots?Xylem. Its dead, lignified vessels and tracheids conduct water, while phloem carries sugars from the leaves.

How it works

Upload your biology notes

Add a PDF, DOCX, PPTX, plain text file or photos of pages for the chapters you need for NEET 2025.

Practice and review mistakes

Frequently asked questions

How should I study NEET biology in the final weeks?

Alternate short timed quizzes with reviews of every wrong answer, and return to topics like genetics and plant physiology that you still miss. Spacing your sessions across days helps more than one long cram session.

Which NEET biology topics do students most often miss in practice quizzes?

Students often lose marks on fine details in genetics, human physiology and ecology, where similar terms and processes are easy to confuse. Writing short explanations of wrong answers helps separate them.

Can I export my quiz to PDF or DOCX?

Exports are paid features. PDF and DOCX export are included in the Plus plan, which is $39/year or $7.99/month, and students get 40% off with a school email.

Can I export to Moodle XML or QTI 2.1?

Yes, but only on the Pro plan at $14.99/month, which also includes a stronger AI model and bulk upload. The free plan lets you study in the browser without exports.
