Looking something up is a skill you drill: start from the topic and the defined terms, read the rule in its context, then check conditions, exceptions and cross-references.
Open book is a speed test on finding things, and finding a number you recognise is not the same as finding the rule that governs your situation.
It is lessons 14, 15 and 16 run as a drill. Structure gets you to the article. Definitions decide what the words mean. Context, conditions and exceptions decide whether the rule you found is the rule that applies. Done repeatedly, the sequence stops costing thought and starts costing seconds.
Check yourself: You found a number that looks like the answer. Are you finished?
Answer: No. Practise explaining why the rule applies, not just finding a familiar number.
Recognising a number means you have seen it before. Being able to say why it governs this situation means you have read the rule, its conditions and its exceptions -- and only the second survives a question designed to catch the first.
