Focus on:

• Expansion and Contraction of Supply
• Increase and Decrease in Supply

This allows efficient syllabus coverage.

4. Central Problems of an Economy

From the introductory chapter, students should not ignore the basic economic problems.

Important concepts include:

These concepts are often tested through conceptual MCQs and case-based questions.

Cost is one of the most important chapters from the examination perspective.

Special attention should be given to relationships among:

• TFC, TVC and TC
• AFC, AVC and AC
• AC and MC
• AVC and MC

Many students memorize definitions but ignore relationships, which is where ICAI often frames questions.

6. Revenue Relationships

The Revenue chapter is relatively short but highly important.

Students should master:

TR and MR Relationship

Understand how Total Revenue changes with Marginal Revenue under different market situations.

AR and MR Relationship

Questions frequently test conceptual understanding of these two revenue measures.

Equilibrium is one of the most valuable topics across the syllabus.

Consumer Equilibrium

Focus on:

Producer Equilibrium

Focus on:

• MC-MR Approach

Macroeconomic Equilibrium

Understand:

• AD-AS Framework
• Saving-Investment Equilibrium
• Two-Sector Economy

• Four-Sector Economy

This area contains several formulas and concepts that are frequently examined.

8. Market Mechanism and Price Determination

Students should understand how equilibrium price changes when:

• Demand changes
• Supply changes
• Both Demand and Supply change

Questions often test the impact on:

• Equilibrium Price
• Equilibrium Quantity

Understanding diagrams can significantly improve accuracy.

9. Perfect Competition

Among all market structures, Perfect Competition receives considerable attention.

Important features include:

• Large Number of Buyers and Sellers

10. National Income and Macroeconomic Policies

National Income

Focus especially on:

• Private Income

Students often focus only on GDP and National Income, while ICAI frequently tests advanced income aggregates.

Monetary Policy vs Fiscal Policy

Prepare these topics comparatively.

Understand:

• Monetary Policy Instruments
• Fiscal Policy Instruments
• Role of RBI
• Role of Government
• Inflation Control Measures
• Economic Growth Measures

Difference-based MCQs are regularly asked.

International Trade and Indian Economy

For International Trade, students should focus on definitions and core concepts.

For Indian Economy, a thorough revision is sufficient, but it should not consume a disproportionate amount of study time compared to higher-weightage chapters.

Final Preparation Strategy

Students aiming for strong marks in CA Foundation Economics September 2026 should prioritize:

1. Demand
2. Elasticity
3. Cost
4. Revenue
5. Equilibrium
6. National Income
