I assume you mean the advanced info. It does say at the bottom that other topics may appear as "lower tariff questions", which my teachers interpreted as meaning 1-2 mark questions. So if you're happy to miss out on the 1-2 mark questions, do so at your own peril. I'd be wary of this though considering the multiple choice questions are all "low tariff"/1 mark despite still needing the same amount of working out as 4-5 mark questions sometimes.
