Here are a few things that help me. Always read the question carefully - circle or underline key points. I write all over my tests like a crazy person, complete with diagrams, to help me organize my thoughts. I'm sure my teachers are amused marking my tests! Hopefully they're good for a laugh or two! Think about what the answer(s) is before looking at the options listed. This is especially helpful for multiple choice questions because sometimes all the options look correct! Be sure you are not assuming anything. I seem to do this often, especially if it is a very generalized question. I tend to read more into the scenario than is actually written there. Also, don't rely on memorization. Memorization is not the same as comprehension. If you only memorize the info, it can sometimes be tricky applying it. And finally, take your time & don't doubt yourself. If you find yourself going over your test & changing a lot of answers - STOP! Don't second guess, your first instinct is often right; only change an answer if you are sure you made a mistake. I have a hard time with this type of test, but am beginning to notice patterns with my thinking. If you can, go over your tests & review all the questions that you got wrong. Was it the wording, did you misunderstand something, did you assume... look for your own patterns in thinking (or misthinking as the case may be). Learn from your mistakes. Part of critical thinking is being able to analyze - that includes self-analysis. I'm told critical thinking skills can improve with experience. Good luck!
