I think it will be mostly on topic 2 and 5.Last year there was basically nothing on these topics as it was mostly topic 4 so I think this is a safe bet.I think the reflex arc will be a six marker

thank god cuz i absolutely hate topic 4 but i love topic 5. apparently monoclonal antibodies might be our 6 marker
