YouTube
YouTube is an excellent IB resource because it offers diverse, high-quality educational content for free. Many IB-specific channels, such as Kognity IB, Chris Doner (IB Physics), Andrew Wiles (IB Biology), IB Blueprint, The Organic Chemistry Tutor, etc., provide subject-specific explanations that align with the IB syllabus. These videos break down complex topics into engaging, easy-to-understand lessons. Many videos often contain diagrams, case studies, and real-world applications of IB concepts, allowing students to have an engaging learning experience.
Additionally, many past paper analyses, mark scheme breakdowns, and study tips from IB graduates can be found on various YouTube channels, such as Hoothematic for IB Math and Alexis Loveraz for revision strategies, among others. YouTube also has many resources for TOK and EE guidance, such as how to follow a correct format and make the work engaging for the reader. A benefit of YouTube tutorials is that they can be replayed as many times as necessary, unlike in a traditional classroom where the teacher may only discuss the information once or twice. This is very helpful to students who may need some more time to grasp concepts.
Khan Academy
Khan Academy is a great IB resource because it provides free, high-quality educational content that aligns well with many IB subjects, especially Mathematics, Sciences, and Economics. Its structured lessons include video explanations, practice exercises, and quizzes that help reinforce learning. The lessons take a step-by-step approach that is very useful for IB students who like to space out the work and ensure early concepts are thoroughly understood before new ones are learned.
For example in IB Math, Khan Academy covers key topics like calculus, statistics, and algebra, which are essential for IB Math AA and AI. In Sciences such as Physics, Chemistry, and Biology, the platform offers clear explanations and interactive problem-solving exercises. Additionally, IB students taking Economics can benefit from its well-structured micro and macroeconomics lessons. Similar benefits and structured lesson plans are available for a wide range of other IB subjects. Khan Academy’s self-paced learning allows students to track their progress, revisit challenging topics, and prepare for exams effectively.
Reddit is a valuable IB resource because it provides fast support, study tips, and advice from current and former IB students. The r/IBO subreddit is one of the most active IB communities, where students can ask questions, discuss difficult concepts, and find motivation during stressful periods in the IB Program.
Reddit fosters peer-to-peer learning where students share information such as study guides, IA/EE/TOK advice, exam strategies and personal insights that may not necessarily be found in formal IB resources such as those mentioned above. Students often discuss and share past papers, mark schemes, and subject-specific resources, thus fostering a strong learning community.
Additionally, IB graduates frequently post advice on time management, stress reduction, and university applications, helping current students navigate the challenges of the IB program. Since hundreds of students post on Reddit every day, there are likely to be fresh insights and support compared to other resources that may be updated less frequently.
We hope you found this post helpful. For more useful materials associated with the IB check out the wide variety of IA, EE and TOK exemplars available at Clastify and other guides available on our blog.
