In Turkey, the LGS (Liselere Geçiş Sınavı) is the national high school entrance exam that every 8th grader faces each June. Science (Fen Bilimleri) accounts for 20 of its 90 questions, yet many students leave it on autopilot while focusing on maths and Turkish. For the LGS 2027 cohort, that is a missed opportunity: science is one of the fastest subjects to improve with a systematic approach.
This guide answers one practical question — how to study for LGS science — with a five-step system, a sample weekly plan and the tactics that raise scores. It also breaks down the seven science units the exam draws from.
LGS science rewards students who interpret experiments, graphs and tables rather than memorise facts — which makes it one of the most improvable sections of the exam.
What Is LGS Science and Why It Matters
The LGS is the Turkish high school entrance exam taken by 8th-grade students across the country; results determine placement in selective high schools. The exam has two sections: verbal (Turkish, history, religion and ethics, English) and numerical — 20 maths and 20 science questions in 80 minutes. Science is half of the numerical section, and its questions can swing both the total score and a student's ranking.
Since 2018, LGS science exam questions have been built around skills rather than recall: items present experimental setups, charts, tables and real-life scenarios and ask students to reason about them. Two students who "know" the same content can end up with very different scores.
LGS Science Topics: The Seven Units
The 8th-grade science curriculum in Turkey has seven units, and all 20 exam questions come from them:
- Seasons and Climate (Mevsimler ve İklim): how seasons form, climate and weather events, global climate change
- DNA and Genetic Code (DNA ve Genetik Kod): inheritance, mutation and modification, adaptation, biotechnology
- Pressure (Basınç): pressure in solids, liquids and gases, and its everyday applications
- Matter and Industry (Madde ve Endüstri): the periodic table, physical and chemical changes, chemical reactions, acids and bases, mixtures
- Simple Machines (Basit Makineler): levers, pulleys, inclined planes, winches and gears
- Energy Transformations and Environmental Science (Enerji Dönüşümleri ve Çevre Bilimi): energy conversions, matter cycles, sustainable development
- Electric Charges and Electrical Energy (Elektrik Yükleri ve Elektrik Enerjisi): static electricity, electric current, resistance and energy conversion
The exact distribution shifts slightly from year to year, but Matter and Industry and DNA and Genetic Code are usually the most heavily weighted — so never skip a unit; invest extra revision where questions cluster.
How to Study for LGS Science: A Five-Step System
The five steps below turn science study into a cycle of understanding, practice, measurement and revision — run them in order and repeat weekly.
1. Run a Diagnostic and List Your Gaps
Before solving random questions, measure where you stand: take a short 10-15 question test for each unit and list your mistakes unit by unit. The units with the most errors get the most study time.
2. Learn Topics Through Everyday Life and Experiments
Science is the subject of daily life. When you study pressure, think about how a straw works; when you study electricity, think about circuit breakers at home. Summarise each topic in your own words and draw small concept maps — this directly builds the interpretation skills the exam rewards.
3. Solve Unit-by-Unit Questions and Keep an Error Notebook
After each topic, solve questions in order of difficulty. For every wrong answer, write down why: a knowledge gap, carelessness, or a misread question. Re-solve your error notebook at the weekend — eliminating repeated mistakes is the fastest way to lift your score.
4. Measure With Mock Exams and Analyse Every One
From September, take one timed 20-question mock per week under real exam conditions. Then spend at least 30 minutes on analysis: group mistakes by unit and question type and update next week's plan. A mock exam without analysis is just a number.
5. Use Spaced Revision to Make Knowledge Stick
Revise each topic briefly after 1 day, 1 week and 1 month. Spaced revision prevents the "I forgot everything" panic of studying once and moving on.
A Sample Weekly Study Plan for LGS Science
You do not need more than 1-1.5 hours a day on science — you need a stable weekly rhythm that fits around school:
- Monday and Wednesday: 40 minutes of new topic learning + 20 minutes of questions on that unit
- Tuesday and Thursday: 30 minutes of error-notebook revision + 30 minutes of mixed questions
- Friday: a 20-question mini test on the week's topics
- Saturday: one timed science mock
- Sunday: mock analysis, goal check and next week's planning
Five Tactics That Raise Your LGS Science Score
- Learn to skip hard questions: flag and move on; the remaining questions deserve your time.
- Practise reading graphs and tables: pay extra attention to items built on charts and experimental setups.
- Master variables in experiments: identify the dependent, independent and controlled variables before answering.
- Derive formulas from units: unit tracking helps you reconstruct a formula under pressure.
- Test yourself weekly: same day, same conditions — track progress in numbers, not feelings.
How BenimRobot Helps You Study LGS Science
BenimRobot is an AI-powered study platform for the Turkish education system; its tools fit every step of the cycle above. With AI question generation you can create unlimited science questions for any unit, aligned with the MEB curriculum and adjustable by difficulty. When you get stuck, the AI solver walks through the solution step by step, teaching reasoning instead of just answers. The optical reader and exam analysis then report your mocks unit by unit, so your weekly plan is driven by data, not guesswork.
Open BenimRobot today, run your science diagnostic and start the 2027 LGS year with a plan — science can become your strongest subject.
Frequently Asked Questions
How many science questions are on the LGS?
Twenty. Science forms half of the numerical section, which has 40 questions in 80 minutes.
When should students start studying for LGS science?
At the start of 8th grade. A steady routine established in September makes the spring exam period far more manageable.
Is LGS science memorisation-based?
No. The questions test interpretation, so understanding concepts and linking them to everyday life beats memorising facts.
How many science questions should a student solve per day?
Consistency matters more than volume: around 15-20 quality questions a day, with regular error-notebook revision, is enough.
Which resources help most for LGS science?
MEB kazanım tests, one reliable topic book and one question bank matched to your level. Finish the resources you have before buying more.
Conclusion: With the Right System, Science Can Be Your Strongest Subject
LGS science study is a repeatable cycle: diagnose your gaps, learn through understanding, practise consistently, analyse every mock and revise in spaced intervals. Students who build this system in the autumn protect an advantage by spring. Start this week — run your diagnostic, set up your weekly plan and watch your science score follow.
