These model papers apply to composite annual exams starting from 2026 and onwards, and this post explains exactly what has changed, which subjects are covered, and how to prepare using the resources shared below.
Covered Subjects Under the New Curriculum 2022 to 2023
The new Practical Based Assessment currently covers four subjects from the Science group.
New PBA Status and Pattern
The new PBA is built around the Curriculum 2022 to 2023, which is Student Learning Outcome focused while still integrating elements from the Scheme of Studies 2006. Understanding the overall pattern before diving into practice papers makes preparation far more efficient.
- Total marks are 30 for most subjects, while Computer Science carries 50 marks.
- The time allowed for the paper is 2 hours and 30 minutes.
- The paper is divided into two sections. Section A covers the main practical tasks and carries 18 marks, while Section B covers short questions and carries 12 marks.
- The overall focus stays on experiments, calculations, graphs, and analysis rather than pure theory.
- Complete PDFs of the model papers can be downloaded directly from the official FBISE website.

FBISE Class 12 New PBA Pattern and Instructions, 2022 to 2023 Scheme
The purpose of this assessment is to measure practical skills through experiments, observations, calculations, and diagrams rather than relying only on written theory.
Format: Section A focuses on experiments and data tables and is worth 18 marks, while Section B consists of short questions worth 12 marks.
Instructions: Students must answer within the spaces provided on the paper, use a black or blue pen only, and calculators are not permitted during the assessment.
Subjects: This new PBA format currently applies only to the Science group, covering Physics, Chemistry, Biology, and Computer Science.

Sample Physics New PBA Content, 2022 to 2023 Scheme
To give students an idea of what to expect, here is a sample question based on using a potentiometer to determine the internal resistance of a cell in the lab.
i. What is the principle behind using a potentiometer to measure internal resistance? (01 mark) ii. Why is the potentiometer preferred for measuring the internal resistance of a cell? (01 mark) iii.
The model paper provides a data table for the null deflection method, with columns for the number of observations, the resistance R used, the length of the balance point without R, the length of the balance point with R, the difference of lengths, the calculated internal resistance r, and the units for each quantity.
Students are asked to copy this table and complete the missing entries based on the readings given. (03 marks) iv. How do you determine the emf of a cell using a potentiometer? (01 mark)
Similar practical style questions appear across the other subjects as well. Chemistry papers include tasks such as salt analysis and titration.
Biology papers include experiments such as testing for catalase activity and antibiotic sensitivity, and Computer Science papers include writing Python code and building a minimum viable product for a store style application.
Preparation Tips for New FBISE Class 12 PBA, 2022 to 2023 Scheme
- Focus on Student Learning Outcome based experiments, such as using a potentiometer to measure resistance or a spherometer to measure curvature.
- Practice building data tables, performing calculations, plotting graphs, and working out percentage error.
- Make sure you understand the underlying principle, the expected effect, and the correct way to record observations for each experiment, rather than memorizing answers without understanding the reasoning behind them.
- Keep in mind that this new pattern applies to annual exams from 2026 onwards, so it is worth practicing with the updated model papers rather than older practical papers based on the previous scheme.

Conclusion
The new FBISE PBA model papers give Class 12 Science group students a clear picture of what to expect under the Curriculum 2022 to 2023, from the overall marks distribution down to the exact style of experiment based questions. With official model papers now available directly from FBISE, along with experiment wise guides and past solutions from HSA Notes, students have everything they need to prepare with confidence well before the 2026 annual exams begin.
