What med students ask her most often:
  • There is so much material to cover. Can you help me stay organized and on track to test well?
  • How do I know when I'm exam-ready?
  • It is hard for me to concentrate when I study. What are the best ways to stay focused?
  • How can I overcome test-anxiety?
Mary's advice:
  • Break down seemingly insurmountable tasks into many mini-tasks. This helps to show you've accomplished something, and the task is done. It also helps to encourage you to start the next one. A task that is attainable is always easier to start than one that appears too difficult at the onset.
  • Paraphrase what you read. Put it in your own words. Digest it. Own it. Record yourself. Play back when exercising, resting, driving…
  • Remove your distractions. What is hindering you from getting started with your studies each day? What prevents you from keeping focused? What pulls you away from concentrated studies? Turn off the cell phone, and sign off all computer alerts during study hours.
  • "Exceptions to the Rule" are abundant in medicine and require understanding the concept behind the fact. Don't be discouraged if this is hard to grasp at first. It takes practice to become familiar with this testing method.
