The Biology Practice Test measures your understanding of modern biological concepts, processes, and systems — skills essential for scientific reasoning, research, and higher education in the life sciences. It evaluates how effectively you can apply knowledge about cells, genetics, energy flow, organismal systems, and evolution.
This section of the DOST-SEI JLSS Qualifying Examination focuses on reasoning through biological concepts rather than memorization.

After answering, correct answers will appear in green, while incorrect ones will show in red, helping you learn and improve as you go.
About This Practice Test
This Biology practice test is composed of multiple-choice questions designed to challenge your understanding of the foundations of life science. Each question requires careful analysis to determine which option best explains a process, identifies a structure, or predicts an experimental outcome.
You may encounter the following types of questions:
- Cell Biology and Transport – identification of organelles, stages of the cell cycle, and membrane transport mechanisms
- Energy Transformation – photosynthesis, cellular respiration, enzymes, and metabolic pathways
- Organismal Biology – anatomy and physiology of major organ systems, development, and homeostasis
- Genetics – Mendelian inheritance, Punnett squares, DNA replication, transcription, translation, and population genetics
- Evolution and Diversity – natural selection, adaptation, classification, and evolutionary relationships among organisms
These topics test your conceptual understanding, reasoning ability, and application of biological principles. Regular practice helps strengthen your recall, interpretation, and critical analysis of biological phenomena.
Study Tips for the Biology Test
If you are preparing for the DOST-SEI JLSS, consistent and focused study will yield the best results. Here are some practical tips to help you prepare:
- Practice regularly. Schedule short, focused review sessions each week to improve long-term retention.
- Master core processes. Prioritize high-yield concepts like cell division, photosynthesis, respiration, and the central dogma.
- Use diagrams and flowcharts. Visualize systems and cycles to better understand relationships between processes.
- Drill genetics problems. Practice Punnett squares, probability, and inheritance patterns to become more confident.
- Label and interpret figures. Be comfortable with diagrams of cells, organ systems, and life cycles — these are common in exams.
- Understand experiments. Practice reading short experimental setups and predicting possible outcomes.
- Review your mistakes. Revisit every wrong answer to identify conceptual gaps and strengthen your foundation.
Tips During the Actual Exam
On test day, apply these strategies to answer efficiently and accurately:
- Read each question carefully. Identify what is being asked before checking the answer choices.
- Eliminate wrong options. Remove choices that contradict basic biological principles to narrow your selection.
- Analyze diagrams. Many questions rely on visual interpretation — check labels, directions, and symbols.
- Organize calculations. Use scratch paper for genetic crosses and ratio problems to avoid confusion.
- Manage your time. Spend roughly the same amount of time per item; skip and return to harder ones if needed.
- Rely on logic. When uncertain, pick the answer most consistent with scientific reasoning.
- Stay composed. Deep breathing and steady focus help prevent careless errors.
Final Reminder
Biology is about understanding connections between processes, not just recalling facts. Focus on how systems interact — from molecules to organisms — and practice interpreting real-world examples.
Take this practice test as many times as you need, review your mistakes carefully, and track your improvement over time. With regular study and focus, you can confidently face the Biology section of the DOST-SEI JLSS exam.
