IB Physics: Expert Advice from Tutors
What is IB Physics?
IB physics is a notably challenging course for IBDP students. As described by the IB themselves, IB physics test candidates on both their understanding of the theoretical and practical aspects of physics as well as how experts in the field develop knowledge claims and the limitations of the method used.
The IB physics curriculum is grouped into five topics, with between four and five sub-topics each. The five main topics are as follows:
Space, time and motion
The particulate nature of matter
Wave behaviour
Fields
Nuclear and quantum physics
As would be expected, IB physics is deeply rooted in mathematics, with data analysis singled out as an essential skill for those looking to score highly. For learners who wish to study subjects such as mechanical engineering, architecture, astronomy, or geophysics at university level, IB physics is an essential DP component.
Should I Take IB Physics HL or SL?
As with any subject, it can be difficult to decide between IB physics Higher Level or Standard Level. For IB candidates interested in taking physics as one of their DP course, it can be useful to consider two points:
How strong is your interest in IB physics?
What is your goal in studying IB physics?
Regarding this first question, potential IB physics learners must recognise to what extent they are interested in the subject, which leads on to the second question regarding learning outcomes. For those who wish to explore IB physics as a means to gain a broad scientific education, possibly rounded out by chemistry and/or biology, then SL physics may be a good fit. However, for students aiming to pursue a career in the field or in related fields, it is recommended that they take IB physics HL.
What Are the Particular Challenges of IB Physics?
The IB physics course holds a number of unique challenges for both SL and HL students. Here, we’ll focus on two difficulties flagged as the most common sticking points for physics learners.
The first notable challenge for IB physics candidates is the high level of mathematical skill required to excel. For those considering the subjects as one of their DP components, the expectations with regard to mathematical competency can often be the deciding factor.
The second standout challenge for those studying IB physics is the abstract nature of certain topics. Concepts of quantum mechanics and electromagnetism can seem impenetrable due to their perceived distance from daily life. For this reason, real-world examples and analogies can be essential to breaking down concepts and relating them to a student’s life.
How Is IB Physics Assessed?
The IB physics course is assessed both externally and internally.
Regarding external assessment, both SL and HL students must complete two exam papers. Paper 1 is divided into two parts (A) and (B), consisting of multiple-choice questions and data-based questions, respectively. Standard Level students have 1.5 hours to complete their paper 1, while HL have 2 hours. For both SL and HL, paper 1 is worth 36% of their total grade.
For paper 2, which concerns short-answer and extended-response questions, SL are given 1.5 hours and HL have 2.5 hours to complete the exam. This paper is worth 44% for SL and HL candidates.
The internally assessed portion of the course is worth the final 20%. Both SL and HL IB physics candidates must complete a scientific investigation of no more than 3,000 words. For this task, candidates must gather and analyse data in order to answer a self-generated research question.
Developing Good IB Physics Study Habits
Developing good study habits is crucial to succeeding in all IB subjects, not only IB physics. While it may seem difficult to get started, if candidates follow a few simple recommendations they are likely to find their study sessions are more productive.
For example, contrary to popular belief, revising one topic for hours on end is not recommended. Doing so will only result in fatigue and disengagement. Rather, IB physics students build a revision schedule that incorporates at least two different topics per session. Moreover, work on the day’s chosen topics should transition between consolidation of knowledge and exam-style questions. This method of revision means that more content is covered and a candidate’s attention is better maintained throughout the session.
Additionally, IB physics learners should make use of past papers and mark schemes. As previously mentioned, time should be spent during each revision session working on exam-style questions. Candidates should familiarise themselves with the format of the exam papers and the types of questions asked. It’s not enough to stick to questions that, while they may be in an exam style, are all from a textbook. Mark schemes are also useful as they offer those studying IB physics a clear idea of what examiners are looking for and how best answers can be presented to achieve maximum marks.
Lastly, while often overlooked, it is important to take time to rest and recharge. Spending hours upon hours revising the physics curriculum with little or no time to unwind is untenable and will cause more harm than good. So, it is important to factor in downtime into each day’s study plan.
Common Mistakes from IB Physics Students
There are a number of mistakes common among both HL and SL IB physics students. First and foremost is forgetting to check your workings. In the same way that an essay must be proofread before submission, IB physics learners should closely examine their answers after completion of a question or before the end of an exam. Avoiding this practice may mean marks are lost due to minor computational errors.
Another issue is timing. As with an exam-based subject, IB physics students must develop time management skills that allow them to complete their test papers in the time allotted. This is easier said than done as the IB physics exams are challenging and often push learners to their limits. Study sessions should, therefore, incorporate timed practice tests so that candidates become confident in their ability to complete exam papers on time.
Last but not least, be sure to focus on key concepts. While it may make sense to pay greater attention to those more complex topics that are a sticking point for many learners, key concepts also require attention. Only when a candidate has grasped the fundamental concepts can they truly tackle the more difficult aspects of a subject.
