For a student to be an effective critical thinker, what first must be understood is the type of learner he or she is. Any student can memorize and learn a concept, but applying that concept in any situation requires critical thinking.
Different teachers teach you the same concepts in different ways. After a while, you have a lot of information swirling around in your mind. In order to be an effective thinker and test taker, it is important that you consolidate. Consolidation will help you classify quicker questions on the test quicker. If you don't classify the questions, you may have to reread the passage again and again, as opposed to directly to the context classified by the question.
Plus, consolidation helps you deal with your working memory. Clump similar things into one spot or shelf. Write things down and classify them. Classification also helps with understanding and memorize things, thus retrieving information faster during the test.
