Treat this sample as a diagnostic. Answer honestly, check the explanation after every question, and note which topics feel shaky. A short, focused review of those topics is worth more than re-reading everything — and the full set lets you drill them topic by topic.
A good way to use this page: take the whole sample in one sitting, then go back over every explanation with fresh eyes. Mark the topics that felt uncertain, not just the ones you got wrong — uncertain answers are unmarked risk on the real exam. One or two focused passes like this usually move a score more than days of passive reading.
