✅ What is Advance Mathematics?
Advance Maths includes those topics from mathematics that go beyond basic arithmetic and number systems. Typically, it involves chapters that are geometry-based, formula-oriented, and concept-heavy, requiring good conceptual clarity and frequent practice.
📌 Why Focus on Advance Maths?
| Reason | Explanation |
|---|---|
| High weightage | SSC CGL Tier-I & Tier-II often include 7-10 questions from Advance Maths. |
| Scoring potential | Well-practiced concepts can fetch you quick and accurate marks. |
| Conceptual clarity = Accuracy | Once understood, these questions become predictable and easy. |
| Less competition | Many candidates skip Advance Maths. Mastering it gives you a competitive edge. |

📘 Tip: Keep a separate geometry formula notebook and revise diagrams regularly.
3️⃣ Mensuration:
This is a formula-based chapter. Mug up the formulas and practice different models.
2D Figures:
- Square, Rectangle, Triangle, Circle, Trapezium, Parallelogram
3D Figures:
- Cube, Cuboid, Cylinder, Cone, Sphere, Hemisphere
| Shape | Area | Volume |
|---|---|---|
| Square | a² | — |
| Rectangle | l × b | — |
| Circle | πr² | — |
| Cube | 6a² | a³ |
| Cuboid | 2(lb + bh + hl) | l × b × h |
| Cylinder | 2πr(h + r) | πr²h |
📌 Tip: Focus more on Cylinders and Cones, they appear frequently in SSC exams.
4️⃣ Trigonometry:
Trigonometry is one of the most feared topics, but it is actually repetitive in nature.
Important Topics:
- Trigonometric Ratios
- Trigonometric Identities
- Heights & Distances
- Values of Standard Angles (0°, 30°, 45°, 60°, 90°)
Value Chart:
| θ | sin θ | cos θ | tan θ |
|---|---|---|---|
| 0° | 0 | 1 | 0 |
| 30° | 1/2 | √3/2 | 1/√3 |
| 45° | √2/2 | √2/2 | 1 |
| 60° | √3/2 | 1/2 | √3 |
| 90° | 1 | 0 | ∞ |
🎯 Tip: Learn all identities and practice Height & Distance questions with diagrams.
5️⃣ Co-ordinate Geometry:
Though not very frequent, it is important for Tier-II SSC exams and state exams.
Key Concepts:
- Distance Formula: √[(x₂ – x₁)² + (y₂ – y₁)²]
- Section Formula
- Midpoint Formula
- Area of Triangle using coordinates
📌 Tip: Practice simple questions regularly to avoid silly mistakes.
6️⃣ Heights and Distances:
A small but easy sub-topic under trigonometry.
Most Common Scenarios:
- Angle of Elevation
- Angle of Depression
- Use of right triangle and trigonometric ratios
📌 Tip: Draw diagrams to understand and solve questions quickly.
