While both levels cover foundational concepts, HL includes additional lenses requiring deeper analysis, such as international laws, economic solutions, and ethical perspectives. Furthermore, the assessment load differs significantly: SL students face 3 hours of exams, whereas HL students have 4.5 hours.

A top-scoring IA starts with a unique, focused research question rather than a generic topic. You should aim to collect primary data with at least 25 data points to ensure reliability. Finally, ensure your conclusion directly answers your research question and evaluates your hypothesis.

Our experts recommend prioritizing content revision and exam technique over passive learning. This includes analyzing data and graphs, memorizing case studies to support long-answer questions, and strictly adhering to the specific command terms used in IB questions.

Our tutors are high-achieving IB graduates who can help you master the specific "cryptic" language of IB markschemes and improve your exam technique. We provide personalized support for understanding complex systems, structuring your IA, and building the confidence to handle data-based questions.

The consultation is a free, 20–30 minute session with a Student Success Expert designed to identify your specific needs. You will receive a clear action plan, priorities for your revision, and advice on next steps, with absolutely no obligation to purchase tutoring.
