Congratulations on getting this far in your career, but now is the most important part. You need to be confident in yourself. You simply cannot compare the two. Everybody tests differently under stress. There are many factors that can affect how you perform on your exam. Keep doing what you are doing, review information you know will be on the exam, and do lots of practice questions each day leading up until one or two days before the exam. I recommend not studying the day before your exam as your brain needs time to rest and prepare for your exam. Remember, this exam tests your critical thinking abilities. If your mind is in the right place and you are confident, you will be able to critically think through each question. Take your time on the exam. Good luck!
