"Rangkuman materi" can be a double-edged sword. For OSN Biology, which tests analytical depth and problem-solving (not just memorization), a summary alone is insufficient. However, a is invaluable for last-minute revision and connecting concepts. The rangkuman did not warn you about pepsinogen
Use existing rangkuman as a checklist. For each bullet point, ask: "Can I explain this in 3 sentences to a friend?" If no, go back to textbook.
