IB Subject Selection: The Complete Guide

The main difference lies in depth and time. HL subjects require approximately 240 teaching hours and cover core concepts plus specific extension topics focusing on complexity. SL subjects require about 150 hours and focus on breadth. Universities view HLs as evidence that you are ready for university-level study in that specific field.

We recommend the "University Backwards" method. Certain degrees have non-negotiable requirements. For example, Medicine almost always requires Chemistry HL and often Biology HL. Engineering usually demands Physics and Math AA HL. Always check specific university requirements to avoid closing academic pathways.

If you are undecided, use our "Interest-Audit" framework. Identify subjects where you experience "flow" (time passes quickly) and cross-reference them with your highest grades from the last two years. Crucially, strictly avoid subjects you dislike, as the IB is too rigorous to survive without genuine motivation.
