Why a custom practice test beats a generic one

Most free biology EOC practice tests online are fixed worksheets written for a general course, so they can miss the terms and emphasis of your own class. A free biology EOC practice test with answers works better when it is built from the exact notes and slides you studied, because every question points back to material you need to know.

  • Questions drawn from your teacher's slides, notes and textbook pages
  • Multiple choice, true/false and short answer in one set
  • Explanations for every answer so mistakes become study points
  • Flashcards with spaced repetition for terms you keep missing
Example biology EOC practice questions with answers
Which organelle is the main site of aerobic cellular respiration in eukaryotic cells?Mitochondria. They house the Krebs cycle and electron transport chain, which produce most of the cell's ATP.
In a DNA sample, adenine makes up 30% of the bases. What percentage is cytosine?20%. Adenine pairs with thymine, so A and T are each 30%, leaving 40% split equally between G and C.
True or false: Natural selection acts on an organism's phenotype, and the resulting differences in reproduction change allele frequencies in a population.True. Individuals with traits that improve survival or reproduction leave more offspring, shifting the gene pool over generations.
What is the net ATP yield of glycolysis per glucose molecule?2 ATP. Glycolysis spends 2 ATP to start and produces 4, so the net gain is 2, along with 2 NADH.
Which structure gives plant cells rigid support and is made mainly of cellulose?The cell wall. Cellulose fibers resist the pressure of water inside the cell, preventing it from bursting in hypotonic conditions.

Study in the browser on the free plan. PDF and DOCX exports come with Plus, and QTI 2.1 and Moodle XML exports come with Pro.

How it works

Upload your biology notes

Add a PDF, slide deck, DOCX file, text notes or photos of pages. Typed text and printed pages are both read.

Pick question types

Choose multiple choice, true/false or short answer, then generate the set. Free accounts get 3 generations per month.

Take the test and check answers

Work through the questions, read the explanations for anything you missed, and study weak topics with flashcards.

Generate a set from your own files, take it under timed conditions, and use the explanations to review what you got wrong. Repeat with a fresh set before the exam to check whether your understanding holds up on questions you have not seen before.

Frequently asked questions

What topics do biology EOC exams usually cover?

Most biology end-of-course exams cover cell structure and function, genetics, evolution, ecology and energy flow in living systems. Check your course syllabus or state blueprint for the exact topics and weighting.

How many questions should a biology EOC practice set include?

Shorter sets work well for reviewing a single unit, while a longer set suits a full-course review before the exam. You can generate a new set from the same notes whenever you want to test yourself again.

Can I export my biology practice test?

Exports are paid features. PDF and DOCX exports come with the Plus plan, and QTI 2.1 and Moodle XML exports come with Pro. The free plan lets you study in the browser.
