Are you a First Year (XI) student in Sindh feeling the pressure of the upcoming annual examinations? With the recent rescheduling of the BISE Hyderabad exams to April 21st, 2026, students now have a golden opportunity to refine their preparation. Success in the Sindh Board 11th Class Science Group (Pre-Medical and Pre-Engineering) depends heavily on focusing on high-probability questions and mastering the new 2026 paper pattern.

In this long-form guide, we provide a subject-wise Target Paper for 2026 based on a deep analysis of the last 10 years of past papers from BIEK Karachi, BISE Hyderabad, Mirpurkhas, and Sukkur boards. These questions are handpicked to help you secure 80%+ marks in the theory section.

1. XI Physics Guess Paper 2026 (Science Group)

Physics is a subject of derivations and numericals. For the 2026 Sindh Board exams, the following chapters are essential:

Section B: Short Answer Questions

• Vectors: Show that the scalar product is commutative but the vector product is not. Find the angle between two vectors using the Dot Product.
• Motion: Distinguish between Elastic and Inelastic collisions. Derive the expression for the range of a projectile.
• Work & Energy: Prove the Work-Energy Theorem. Define Absolute Gravitational Potential Energy.
• Waves: Explain Newton’s formula for the speed of sound and Laplace’s correction. What are beats and their uses?

Section C: Detailed Answer Questions (Derivations)

• Projectile Motion: Derive expressions for Maximum Height, Time of Flight, and Horizontal Range. Prove that the range is maximum at 45°.
• Optics: Working and magnifying power of a Compound Microscope or Astronomical Telescope.
• Torque: Define Torque and derive the expression $\tau = rF\sin\theta$. Discuss the first and second conditions of equilibrium.

2. XI Chemistry Important Questions (Pre-Medical/Engineering)

The Chemistry paper often follows a balanced mix of stoichiometry numericals and descriptive inorganic chemistry.

• Atomic Structure: Explain Bohr’s Atomic Model and calculate the radius of the $n^{th}$ orbit of a Hydrogen atom. Discuss Heisenberg’s Uncertainty Principle.
• Chemical Bonding: Explain $sp^3$, $sp^2$, and $sp$ hybridization with examples like Methane, Ethene, and Ethyne.
• Gas Laws: State Graham’s Law of Diffusion and Dalton’s Law of Partial Pressure with applications.
• Chemical Equilibrium: State Le-Chatelier’s Principle. Discuss the effects of change in concentration and pressure on the Haber’s Process.

3. Biology XI Target Paper (Pre-Medical Only)

Biology students must focus on well-labeled diagrams. The 2026 paper is predicted to include:

• Cell Structure: Fluid Mosaic Model of the cell membrane. Compare Prokaryotic vs. Eukaryotic cells.
• Biological Molecules: Define and classify Proteins. Explain the structure of DNA (Double Helix).
• Bioenergetics: Detailed steps of Glycolysis and the Kreb’s Cycle. Describe the Z-scheme of Light reactions.
• Kingdom Animalia: General characteristics of Phylum Arthropoda and Phylum Chordata.

4. Mathematics XI Important Exercises (Pre-Engineering Only)

For Math, practice is everything. Focus on these high-probability exercises from the New Sindh Textbook:

• Complex Numbers: Exercise 1.2 (Multiplicative Inverse and De Moivre’s Theorem).
• Matrices: Exercise 3.3 (Properties of Determinants) and Exercise 3.5 (Cramer’s Rule).
• Trigonometry: Exercise 10.2 (Sum and Difference formulas) and Chapter 12 (General Solutions).
• Probability: Fundamental concepts of permutations and combinations (Ex 7.2, 7.3).

5. English & Islamiat (Compulsory Subjects)

Do not ignore these subjects, as they can significantly boost your overall percentage!

• English: Summaries of “Ozymandias” and “Good Timber.” Learn the CV writing format and focus on Letter Writing to the Editor.
• Islamiat: Translation and Explanation of Ayats from Surah Al-Anfal and Surah Al-Baqarah. The rights of non-Muslims in an Islamic state.

Frequently Asked Questions (FAQs)

Is this guess paper valid for BIEK Karachi?
Yes! While boards differ slightly, the syllabus and paper pattern for 2026 are synchronized across Sindh boards.

Should I study only these questions?
These are the most important questions, but we always advise completing your full textbook once before using this as a final revision tool.
