How to Study Biology for the UTBK

What changed: the TKA brings biology back into PTN selection

Throughout the UTBK-SNBT period from 2023 to 2025, the test-based selection only measured Scholastic Aptitude, Literacy, and Mathematical Reasoning. During that stretch biology was not tested as a standalone subject, so many science-track applicants concentrated fully on scholastic skills. The shift came when the Academic Ability Test was revived and biology re-entered the selection components. In the new structure, the TKA consists of three compulsory subjects, namely Mathematics, Indonesian, and English, plus two elective subjects aligned with the intended major. Biology sits in the elective science group alongside Physics and Chemistry. Applicants to medicine, biology, pharmacy, nutrition, and agriculture commonly place biology as one of their choices because it aligns with their target field. Technical details such as the final question count and the duration of each session still follow official SNPMB announcements and may be adjusted each year. A sensible first step is therefore opening the latest blueprint on the official site, then building a study plan from it. What is already clear is that the emphasis falls on reasoning, which makes concept mastery the decisive foothold.

6 Steps to Prepare UTBK Biology From the Start to Exam Day

These six steps follow a realistic UTBK preparation flow, from mapping the material to managing exam-day conditions. Work through them in order, because each step lays the foothold for the next.

1. 1

   Map priority chapters and build a countdown from the exam date

   Open the official TKA blueprint on the SNPMB site and mark the biology chapters that appear most often, such as cells and metabolism, genetics, and ecology. From there, build a countdown starting from the expected exam date around November. Split the preparation time into three broad phases: concept mastery, per-chapter question practice, then try-outs and consolidation. Mapping at the outset keeps study time aimed at the material that truly counts, and prevents time from draining into chapters that rarely appear. Write measurable weekly targets, for example finishing one chapter cluster every two weeks, so progress is easy to track.

   Tips

   • Refresh the chapter map once the official blueprint for the current year is released on the SNPMB site
   • Reserve the final two to three weeks for try-outs and rest, with no new material
2. 2

   Build concept understanding for each chapter cluster before calculating questions

   UTBK biology assesses reasoning, so its foundation is understanding systems and processes first. For metabolism, make sure the flow of cellular respiration and photosynthesis is clear, along with where each takes place and what it produces. For genetics, master the logic of crosses before moving into more complex question variations. An effective method is re-explaining each process in your own words, then drawing its diagram from memory. Once a concept can be narrated without opening a book, the material is ready to answer analytical questions. This phase feels slow at first, yet it becomes the deciding factor when questions demand applying a concept to a situation never seen before.

   Tips

   • Test understanding by explaining a chapter to a friend or family member
   • Flag shaky concepts to revisit in a spaced review session
   Genetics often feels challenging because students jump to dihybrid crosses before monohybrids are truly mastered, so finish one type until fluent first.
3. 3

   Practise reasoning and HOTS questions for every chapter

   Once a chapter's concept is understood, add plenty of HOTS-style questions that call for analysis and applying concepts. UTBK biology questions often present new cases, experiment results, or statements to be judged true or false based on a concept. Work through questions chapter by chapter first so each material's pattern becomes readable, then mix across chapters to resemble the real exam. When you meet a wrong answer, do more than checking the key. Trace where the error lies: a concept slip, misreading data, or a careless link between pieces of information. Reworking a previously wrong question a few days later yields far stronger results than chasing new questions endlessly without evaluation.

   Tips

   • Group questions by chapter to see which material is still weak
   • Time each question so you get used to the exam pace early
4. 4

   Get used to reading graphs, tables, and experiment data

   A hallmark of UTBK biology questions is presenting information through enzyme rate graphs, cross-result tables, food web diagrams, or population growth curves. The ability to read data quickly is often what separates scores. Train this habit deliberately: watch the graph axes, units, upward or downward trends, and the variables changed and measured in an experiment. Link the data pattern to concepts you already understand, such as how temperature affects enzyme activity or how a change in one population affects the food chain. The more often you practise interpreting data, the faster graph-based questions can be answered with confidence.

   Tips

   • Before looking at the answer choices, write down your own conclusion from the graph or table
   • Collect the graph types that appear often and practise interpreting them regularly
5. 5

   Take regular try-outs then analyse your error patterns

   A try-out is the most honest gauge of UTBK biology readiness. Schedule try-outs regularly, for instance every two weeks during the consolidation phase, under exam-like conditions: limited time, a calm setting, no notes open. Afterward, set aside dedicated time to dissect the results. Note which chapters are often wrong, and whether the slip came from concept, carelessness, or running out of time. Recurring error patterns point to material that needs another review. Through a consistent cycle of try-outs and analysis, scores tend to rise gradually because each round repairs a specific weak point. Keep a score recap to track the trend of progress over time.

   Tips

   • Treat every try-out as mental practice for handling time pressure
   • Draft a short summary of the three biggest mistakes from each try-out to review
   Piling up try-outs without dissecting the results makes the same mistakes recur, so analysis matters far more than simply adding to the count of try-outs.
6. 6

   Manage answering time and your condition before exam day

   In the final weeks, shift the focus from new material to strategy and recovering energy. Practise reading questions quickly, recognising ones you can answer straight away, and flagging hard ones to revisit at the end. This strategy keeps time from draining into a single question. Enough sleep in the days before the exam has a large effect on sharpness of thought, often greater than adding a night of study. Prepare the technical matters too: the exam location, required documents, and the journey there. Calm on exam day helps reasoning work at its best, so months of preparation can come out intact.

   Tips

   • Practise the skip-question strategy during try-outs so it feels natural on exam day
   • Cut down late nights in the final three days to keep your thinking fresh

Studying Biology for a School Test vs for the TKA UTBK

This difference explains why students who excel at school tests still need to adjust how they study when preparing biology for the UTBK.
