Nah doesn't waste time, I go through and slide my pacer over the sentences, and make annotations fairly swiftly. Even if it is slower than the generic reading technique, the "capturing factor" of my technique more than makes up for it.
Checking the whole question and your answer carefully after completing wastes more time than doing this (I know from taking 1 hr 50 mins to finish Methods Exam 2 lol).
And the 2 marks I lost on the Methods exam poses another exam technique problem I'm trying to solve - how do I ensure that if the information I need to answer a question is located on another page, that the probability of incorrectly transcribing the required information is eliminated.
