Navigating the Depths of Physics: A Comprehensive Look at the External Assessment Papers

Physics, often regarded as the fundamental science, explores the fundamental principles governing the universe. In the International Baccalaureate (IB) program, the external assessment of physics plays a pivotal role in evaluating students’ understanding and application of these principles. This assessment consists of three written papers, each designed to challenge and assess students at different levels. In this blog post, we will delve into the intricacies of each paper, shedding light on the diverse question formats and the skills they aim to evaluate.

Paper 1: Multiple-Choice Marvels

The journey into the external assessment begins with Paper 1, a test of knowledge and quick thinking. At Standard Level (SL), students tackle 30 multiple-choice questions, while their Higher Level (HL) counterparts grapple with 40. This section is a true test of a student’s breadth of understanding, requiring them to navigate a diverse range of topics within a limited timeframe.

The multiple-choice format, while seemingly straightforward, demands a deep comprehension of the subject matter. Students must not only identify correct answers but also discern the nuances of various concepts. This paper aims to evaluate their ability to recall facts, apply fundamental principles, and make connections between different areas of physics.

Paper 2: Unraveling the Core and AHL Material

Paper 2 takes students on a more in-depth exploration of the core material, with HL students also venturing into the Additional Higher Level (AHL) content. This section is a blend of short-answer and extended-response questions, demanding a higher level of critical thinking and problem-solving skills.

Short-answer questions require concise yet precise responses, testing students’ ability to articulate their understanding of specific concepts. On the other hand, extended-response questions delve into the application of these concepts in more complex scenarios. Here, students must showcase their analytical skills, demonstrating a deep understanding of the core and AHL material.

This paper not only evaluates knowledge retention but also assesses the ability to apply theoretical concepts to real-world situations. It challenges students to think beyond memorization, fostering a deeper understanding of the subject.

Paper 3: Navigating the Depths with Data

The final leg of the external assessment journey is Paper 3, a multifaceted evaluation of experimental work and option topics. Divided into two sections, this paper presents a unique set of challenges.

Section A focuses on experimental work related to the core (and AHL material at HL). Students are presented with a data-based question and several short-answer questions, testing their ability to analyze experimental data, draw conclusions, and evaluate the precision of their results. This section assesses practical skills and the application of scientific methods.

Section B is a culmination of the four options available, presenting students with short-answer and extended-response questions. Here, students showcase their mastery of specific topics they have chosen to explore in-depth. This section not only evaluates knowledge but also emphasizes the importance of specialization and expertise within the broader field of physics.


The external assessment papers in physics, spanning Papers 1, 2, and 3, collectively provide a comprehensive evaluation of students’ knowledge, analytical skills, and practical application of physics principles. As students navigate the intricate web of multiple-choice questions, short-answer challenges, and experimental evaluations, they not only demonstrate their proficiency but also develop a holistic understanding of the subject.

In the grand tapestry of physics, the external assessment papers serve as a compass, guiding students through the diverse landscapes of theoretical concepts, experimental methodologies, and specialized options. As they conquer each paper, students emerge not only as scholars of physics but as individuals equipped to unravel the mysteries of the universe. The journey may be challenging, but it is in overcoming these challenges that students truly grasp the essence of physics and its profound impact on our understanding of the world.
