Subject-Wise Preparation Strategy
Mathematics (75 Theory)
-
Start with Algebra: It carries 20 marks - the highest single unit. Master Quadratic Equations and AP first since they have the most variety of questions.
-
Geometry and Trigonometry next: Together they carry 27 marks. Practice constructions with a compass and ruler. For Trigonometry, memorize all identities and practice heights and distances problems.
-
Mensuration for guaranteed marks: Surface area and volume problems follow standard formulas. If you memorize the formulas and practice 20 problems, you can score 8-10 marks easily.
-
Objective section strategy: The 5 MCQs carrying 1 mark each are typically from across all units. A student who has revised all chapters at least once will find these straightforward.
Science (75 Theory + 25 Practical)
| Unit | Topics | Approx. Theory Marks |
|---|---|---|
| Chemical Substances | Reactions, Acids-Bases, Metals, Carbon, Periodic Table | 20-22 |
| Living World | Life Processes, Control, Reproduction, Heredity | 20-22 |
| Natural Phenomena | Light, Human Eye | 8-10 |
| Current Effects | Electricity, Magnetism | 8-10 |
| Natural Resources | Energy, Environment, Resources | 6-8 |
Strategy:
- Chemical Reactions and Equations: Practice balancing at least 30 equations.
- Life Processes: Draw and label all diagrams (digestive system, heart, nephron, neuron).
- Electricity: Master Ohm's Law numericals and circuit problems.
- Practical component (25 marks): Complete all assigned experiments. Keep records neat.
Social Science (75 Theory)
| Section | Topics | Approx. Marks |
|---|---|---|
| History | Indian National Movement, print culture, nationalism | 18-20 |
| Geography | Resources, agriculture, minerals, manufacturing, lifelines | 18-20 |
| Political Science | Democracy, federalism, political parties, outcomes | 18-20 |
| Economics | Development, sectors, money, globalization, consumer rights | 15-18 |
Strategy for Hindi medium: Social Science is your highest-scoring opportunity. Write structured answers with clear headings. Use bullet points for listing factors, causes, and effects. Map work requires regular practice - mark important locations on blank India maps weekly.
Hindi Special (75 Theory)
Hindi is the most important subject for CG Board students since it is both the medium of instruction and a major exam subject.
| Section | Component | Approx. Marks |
|---|---|---|
| Gadya (Prose) | Textbook lessons, explanation, summary | 20 |
| Padya (Poetry) | Poem appreciation, bhavarth, explanation | 15 |
| Vyakaran (Grammar) | Sandhi, Samas, Ras, Alankar, Upsarg-Pratyay | 20 |
| Lekhan (Writing) | Essay, letter, paragraph | 15 |
| Apathit Gadyansh | Unseen passage | 5 |
Strategy: Grammar carries 20 marks and is entirely formula-based. Learn the rules for Sandhi, Samas, and Alankar systematically. Lekhan (writing) is a guaranteed scoring area if you practice 5-6 essay topics and letter formats.
English (75 Theory)
| Section | Component | Approx. Marks |
|---|---|---|
| Reading | Comprehension passages | 10-15 |
| Writing | Letter, essay, paragraph, notice | 15-20 |
| Grammar | Tenses, voice, narration, transformation | 15-20 |
| Literature | Textbook-based questions | 20-25 |
Strategy for Hindi medium students: English can be challenging for Hindi medium students. Start with grammar (rules-based, easier to master), then focus on writing formats (letter, essay). For literature, read the textbook summaries and practice answer writing.

How CG Board Differs from MP Board
Since Chhattisgarh was carved from Madhya Pradesh in 2000, students and parents often compare the two boards:
| Feature | CGBSE (Chhattisgarh) | MPBSE (Madhya Pradesh) |
|---|---|---|
| Established | 2001 | 1965 |
| Headquarters | Raipur | Bhopal |
| Theory marks | 75 per subject | 75 per subject |
| Practical/Internal | 25 per subject | 25 per subject |
| Primary medium | Hindi | Hindi |
| Textbooks | CG State Textbook | MP State Textbook |
| NCERT alignment | High | High |
| Exam month | March (typically) | February-March |
| Pass marks | 33% | 33% |
Key similarities: Both boards follow a 75-25 theory-practical split, both are Hindi-medium dominant, and both have strong NCERT alignment. The main differences are in the specific textbooks and some state-specific content in Social Science and Hindi literature.
Key differences: CGBSE tends to have slightly different emphasis in certain Science topics. The Maths blueprint structure also differs. If you have study materials from MP Board, they can supplement your preparation but should not replace CG-specific textbooks.
Month-by-Month Plan (October to March)
| Month | Focus | Daily Hours |
|---|---|---|
| October | Complete remaining syllabus. No chapter should remain unread. | 3-4 hours |
| November | First revision. Make formula sheets for Maths. Write key reactions for Science. | 4-5 hours |
| December | Model paper practice begins. 1 paper per week per subject. | 4-5 hours |
| January | Intensive practice. 2 papers per week. Focus on answer writing quality. | 5-6 hours |
| February | Practical preparation + continued theory revision. | 5-6 hours |
| March | Final light revision. Review formula sheets and diagrams. Stay calm. | 3-4 hours |
