CBSE Class 10 Science: The 30-Day Study Plan That Actually Works
30 days before your board exam. The syllabus feels infinite. Your notes are scattered. Panic is setting in.
Stop.
This plan breaks down exactly what to study, when to study it, and how much time to spend — based on CBSE's actual marking pattern and the topics that appear most frequently in board exams.
Before You Start: Know the Paper Structure
CBSE Class 10 Science (2026 pattern):
- Total marks: 80 (theory) + 20 (internal assessment)

- Numericals on pH (rare but possible)
Day 12: Metals and Non-Metals (4-5 marks)

- Ionic and covalent bonding basics
- Corrosion prevention
Day 13: Carbon and its Compounds (5-6 marks)
- Homologous series
- Nomenclature (IUPAC naming — practice 20 compounds)
- Chemical properties: combustion, oxidation, addition, substitution
- Soaps and detergents
Day 14: Chemistry Revision + PYQ Paper
Solve one complete Chemistry section under timed conditions (45 minutes).
WEEK 3 (Days 15-21): Biology — The Mark Booster
Day 15-16: Life Processes (7-8 marks)
The single highest-scoring Biology chapter:
- Nutrition: photosynthesis equation, digestive system diagram
- Respiration: aerobic vs anaerobic, ATP
- Transportation: heart diagram, double circulation
- Excretion: nephron diagram, urine formation
Draw every diagram at least 3 times from memory.
Day 17-18: Control and Coordination (4-5 marks)
- Nervous system: neuron structure, reflex arc
- Brain diagram and functions
- Hormones in humans and plants (auxin, gibberellin)
- Difference between nervous and hormonal control
Day 19: How Do Organisms Reproduce (5-6 marks)
- Asexual reproduction methods (5 types)
- Male and female reproductive system diagrams
- Menstrual cycle basics
- Contraception methods
Day 20: Heredity and Evolution (4-5 marks)
- Mendel's experiments (monohybrid and dihybrid cross)
- Genotype vs phenotype
- Sex determination in humans
- Evolution basics: homologous vs analogous organs
Day 21: Biology Revision + PYQ Paper
Solve one complete Biology section under timed conditions (50 minutes).
WEEK 4 (Days 22-30): Revision, PYQs, and Exam Strategy
Day 22-23: Remaining Chapters (Quick Coverage)
- Our Environment (3-4 marks): food chains, ozone depletion, biodegradable vs non-biodegradable
- Periodic Classification (3-4 marks): Mendeleev's table, modern periodic table trends
- Sources of Energy (2-3 marks): renewable vs non-renewable, solar cell, nuclear energy
Day 24-25: Diagram Practice Day
Draw every important diagram from memory:
- Human digestive system
- Heart (double circulation)
- Nephron
- Neuron and reflex arc
- Male/female reproductive system
- Human eye
- Electric motor and generator
- Concave mirror ray diagrams
- Convex lens ray diagrams
If you can draw all of these correctly from memory, you've secured 15-20 marks in diagrams alone.
Day 26-27: Full Paper Practice
Solve 2 complete previous year papers under exam conditions:
- 3 hours, no breaks, no phone
- Use answer sheets, not rough paper
- Time yourself per section
Day 28: Weak Area Revision
Based on your mock paper performance, identify your 3 weakest topics and revise only those.
Day 29: Formula Sheet + Quick Revision
- Write down every formula on one page (Physics)
- Write down every reaction on one page (Chemistry)
- Write down every diagram label on one page (Biology)
- Read through these sheets 3 times
Day 30: Light Revision Only
- Read your formula/reaction sheets once
- Solve 10 easy MCQs to build confidence
- Sleep by 10 PM. Seriously.
Exam Day Tips
- Read the paper completely before writing (5 minutes)
- Attempt MCQs first (20 minutes)
- Attempt the questions you're most confident about next
- Draw diagrams with pencil first, then ink
- Write the formula before solving numericals (examiners give marks for formula even if the answer is wrong)
- Attempt every question — there's no negative marking

FAQ
Q: Is 30 days enough to prepare for CBSE Class 10 Science?
A: Yes, if you follow a structured plan and focus on high-weightage chapters first. Many toppers start serious revision only 30-45 days before the exam.
Q: Should I read NCERT or reference books in the last 30 days?
A: NCERT only. Board exams are based on NCERT. Reference books add confusion at this stage. Read NCERT thoroughly and solve PYQs.
Q: How many hours should I study per day?
A: 6-8 hours of focused study with breaks. Quality matters more than quantity. Use the Pomodoro technique: 25 minutes study, 5 minutes break.
Q: What if I haven't started any preparation yet?
A: Focus on the top 5 chapters by weightage (Light, Electricity, Life Processes, Chemical Reactions, Carbon Compounds). These alone cover 40+ marks. Master these first, then expand.
Q: Should I solve sample papers or PYQs?
A: PYQs first, always. They show you the actual exam pattern. Sample papers are useful but less reliable than real past papers.
