>>14415090This is bad advice. Don't measure your ability through your confidence in your answers when skim-reading.
You'd be overconfident in things that you have only a superficial understanding of and you'll be wrongly comfortable about using approaches that initially look appealing but later turn out to be dead-ends. If, for example, you recognize "I need to use integration by parts in this question" but that IBP turns out not to work or that you have to combine IBP with integration by substitution, which you've unwittingly forgotten the formula for, then you don't really know the answer to the question.
You may also sap your confidence by giving yourself the impression that you don't immediately know the answers to the questions, when skimming. But if you could work out the answer when actually sitting down and trying to answer the the question, then you have more skill than you thought.
>>14415080This is far better advice. Measure your ability through your ability to actually answer the questions.
This is exactly why so many students fail by "studying" from YouTube videos. Not to say that YouTube isn't useful for education, but watching the problem get done is like imagining it being done. If you're not actually sitting down and doing it, you'll just end up overconfident and will flounder in the actual exam.
