At SL, prioritise accurate terminology, a clear chain of reasoning, and focused application to the evidence or context provided.
Exam tasks on Truth and Justification reward accurate philosophy terminology, a method that fits the command term, and support from a premise, conclusion, assumption, objection, or counterexample. The response should show how the evidence or example justifies the conclusion rather than merely naming the topic.
Rebuild Truth and Justification from the syllabus heading: define the central idea, identify its place in the unit, and list the subject-specific terms that must be used accurately.
Create one worked explanation using a premise, conclusion, assumption, objection, or counterexample; annotate where the evidence, method, and conclusion connect.
Complete a short IB-style task without notes, then record whether the weakness was knowledge, evidence selection, command-term depth, or evaluation.
