About FSC Mathematics
FSC Mathematics is examined by the Federal Board of Intermediate and Secondary Education (FBISE) in the annual examinations, for 11th and 12th class. Tayyari Karo has real questions from 2023 to 2026, covering topics such as Differentiation, Conic Sections, Vectors, Integration and Functions and Limits. Working through real papers is the fastest way to learn the paper pattern and the way questions are worded.
200 of the questions are multiple choice and marked instantly; the rest are short and long questions with a model answer. The answers are prepared by Tayyari Karo, since we could not find an official marking scheme.

2023 Annual · 11th · Sets/Functions/Groups
If a function f : A → B is such that Range f ≠ B, then f is called an:
- Into function
- One‑one function
- Onto function
- Bijective function
Show answer and explanation
Answer: A. Into function
When the range of f is a proper subset of the co‑domain B (does not cover all of B), f is an into function.
2023 Annual · 11th · Number Systems
The simplified form of (−1)^(23/2) is:
- −1
- 1
- i
- −i
Show answer and explanation
Answer: C. i
(−1)^(23/2) = [(−1)²³]^(1/2) = (−1)^(1/2) = i.
2023 Annual · 11th · Matrices and Determinants
If det A = 5, what is the value of det(15A)? (where order of A is 2×2)
- 75
- 225
- 375
- 1125
Show answer and explanation
Answer: D. 1125
det(kA) = kⁿ det(A) for an n×n matrix. Here n = 2, so det(15A) = 15² × 5 = 225 × 5 = 1125.
2023 Annual · 11th · Quadratic Equations
Use synthetic division to find the values of 'S' and 'T' if (x−1) and (x+2) are factors of the polynomial x³ − Sx² + Tx + 6.
Show model answer
Since (x−1) is a factor, x = 1 is a root: 1 − S + T + 6 = 0 ⇒ T = S − 7 ... (1)
Since (x+2) is a factor, x = −2 is a root: −8 − 4S − 2T + 6 = 0 ⇒ 2S + T = −1 ⇒ T = −1 − 2S ... (2)
Equating (1) and (2): S − 7 = −1 − 2S ⇒ 3S = 6 ⇒ S = 2
Then T = 2 − 7 = −5.
