Maths IIB — Weightage Analysis
Chapter-wise period allocation (from TGBIE Annual Plan 2025-26) and expected question type distribution. Total: 75 marks · 3 hours.
Paper Pattern
Section A — VSAQ
10 questions × 2 marks = 20 marks
All 10 are compulsory
Section B — SAQ
7 questions × 4 marks = 28 marks
Answer any 5
Section C — LAQ
7 questions × 7 marks = 49 marks
Answer any 5
Chapter-wise Weightage
| Chapter | Periods | VSAQ | SAQ | LAQ | Exam Tip |
|---|---|---|---|---|---|
| 1.Circle | 17 | ✓ | ✓ | ✓ | Highest period allocation — guaranteed LAQ. Know tangent conditions and chord of contact. |
| 2.System of Circles | 11 | ✓ | ✓ | — | Radical axis and radical centre — SAQ. Angle between circles — VSAQ. |
| 3.Parabola | 11 | ✓ | ✓ | — | Tangent, normal, and parametric forms — SAQ. Basic standard form — VSAQ. |
| 4.Ellipse | 10 | ✓ | ✓ | — | Eccentricity, foci, latus rectum — VSAQ. Tangent equation — SAQ. |
| 5.Hyperbola | 6 | ✓ | — | — | Asymptotes and basic properties — typically 1 VSAQ. |
| 6.Integration | 17 | ✓ | ✓ | ✓ | Second highest period count — LAQ on integration techniques (by parts, partial fractions, reduction). |
| 7.Definite Integrals | 13 | — | ✓ | ✓ | Properties of definite integrals and area under curves — high LAQ probability. |
| 8.Differential Equations | 12 | ✓ | ✓ | ✓ | Linear DEs and Bernoulli equations — SAQ and LAQ. Order/degree — VSAQ. |
Period count based on TGBIE Annual Plan 2025-26. Higher periods = higher board exam weightage.
High-yield Focus Areas
- 🔴 Circle + Integration (17 periods each) — both have guaranteed LAQs; master both thoroughly
- 🔴 Definite Integrals (13 periods) — properties and area problems are standard LAQ/SAQ
- 🟡 Differential Equations (12 periods) — linear DE and Bernoulli equations appear in SAQ/LAQ
- 🟡 Conics: Parabola + Ellipse (21 combined) — tangent and normal SAQs expected from both
