The IB Chemistry course can seem overwhelming if you are unsure what it comprises. This post is here to provide you with a detailed IB Chemistry guide to help you navigate your way through the course. In this post, we'll discuss key elements of both internal and external assessments of the IB Chemistry course, as well as tips for the Extended Essay, should you choose to complete your EE in Chemistry.
IB Chemistry Guide
General Overview
Syllabus – IB Chemistry is designed to help students understand the principles that govern chemical reactions. The course blends theory with practical investigation, encouraging students to learn chemical concepts and apply them in a laboratory setting. Throughout the course, students explore topics such as atomic structure, bonding, energetics, kinetics, and organic chemistry, while also developing essential skills in data analysis, evaluation, and scientific communication. For a full overview of the IB Chemistry syllabus and the topics covered in each section, check out this post.
Textbooks – To succeed in IB Chemistry, students need a thorough understanding of the course concepts. A good textbook is essential to improving your understanding of IB Chemistry, as it can clearly explain chemistry theory and provide practice questions to help you develop your skills. Our recommended list of IB textbooks can be found here.
Grade boundaries – Although the IB Chemistry grade boundaries change from session to session, it is important that you are familiar with what the approximate range of values can be. This can help you, especially when practicing past papers, as it can show you what grade category you fall into depending on the number of marks you obtain. The latest IB grade boundaries can be found here.
General difficulty – IB Chemistry is considered a moderately challenging science course, as it is easier than IB Physics but more difficult than IB Biology. For a more in-depth view into how hard IB Chemistry is, check out this guide.
Getting the maximum score – The ultimate goal of any IB student is to get the highest score possible. To ensure your success in IB Chemistry, we have compiled some tips to help you get a 7. You can read our suggestions in this post.
Assessment overview – The IB Chemistry course consists of both external exams and internal assessments, which will be outlined in more depth in the section below. For a summary of the IB Chemistry assessment and the IB Chemistry paper weighting, click the links in blue.
External Assessments - Exams
Paper 1 – This paper is split into 2 parts. Part A consists of multiple-choice questions, while Part B consists of data-based and experimental questions. More information about the structure, time limit, weighting, and differences between SL and HL for Paper 1 can be found here.
Paper 2 – This paper consists of short-answer and extended response questions. More information about the structure, time limit, weighting, and differences between SL and HL for Paper 2 can be found here.
Command terms – To succeed in the exams, you must understand what each question type is asking you to do. Command terms such as "Analyze", "Discuss", "Calculate", and "Explain" all have different meanings and require you to structure your answer in a certain way. Browse through our list of command terms to understand what each one means.
Internal Assessment (IA)
Topic ideas – The Chemistry IA allows you to explore a certain research question in depth. A Chemistry IA involves conducting your own experiments and writing a formal lab report. Many topics can be explored in the Chemistry IA. For a detailed list of topic ideas and examples, read our post here. If you need some help getting started, check out this guide on how to start the Chemistry IA.
Criteria – The Chemistry IA is scored against 4 main criteria, such as research design, data analysis, conclusion, and evaluation. For a detailed list of the IB Chemistry IA criteria and a checklist of what to include to maximize your chances of a 7, check out our guide here.
Format and word count – Chemistry IAs should include sections such as an introduction, background information, results, conclusion, and evaluation, etc. For a full guide to the format and structure of a Chemistry IA, including what each section should contain, see this guide. The Chemistry IA should be a maximum of 3000 words. For a guide on how many words each section should be, read this post here.
Mistakes – Common errors such as incomplete background information, poor data analysis, or limited conclusions can prevent you from getting full marks. Check out our guide to the top 10 mistakes students make in the Chemistry IA so you can avoid making the same errors in your IA.
Extended Essay (EE)
Topic ideas – The EE is a 4000-word investigation that allows you to explore a certain research question in depth. Most often, a Chemistry EE involves conducting your own experiments and writing a formal lab report. There is a wide variety of topics you can choose to investigate for your Chemistry EE. For a detailed list of topic ideas and associated examples, read our post here.
Criteria – The EE is scored against 5 criteria that target different aspects of your investigation, such as critical thinking, presentation and engagement. For a detailed list of the IB Chemistry EE criteria and a checklist of what to include to maximize your chances of an A in the EE, check out our guide here.
Format – A well-presented EE can drastically improve your score. Chemistry EEs should include sections such as an introduction, background information, results, evaluation, and conclusion, etc. For a full guide to the format and structure of a Chemistry EE, including what each section should contain, see this guide.
Comparison to Other Science Subjects
Physics – IB Physics and Chemistry are two of the more math-heavy sciences. However, the math in IB Chemistry is simpler to understand than that in IB Physics. IB Chemistry is more application-based, while IB Physics is more theoretical. For a detailed overview of IB Physics and IB Chemistry, including a comparison of course content, who should take these courses, and applicable university majors, read this guide.
Biology – IB Biology is considered more memorization-based and less math-heavy than IB Chemistry. IB Biology is often considered one of the easier sciences, while IB Chemistry is moderately challenging. Both subjects place a strong emphasis on laboratory skills. For a detailed overview of IB Biology and IB Chemistry, including a comparison of course content, who should take these courses, and applicable university majors, read this guide.
