I have never taken a semester of biology yet, and I scored a 77% on the AAMC self-assessment by remembering stuff from high school, eliminating choices based on the passage, and the fact that I have worked as an EMT and ER Scribe at the same time for the past two years, in which I learn a lot about the biological processes of the human body. Should I keep taking practice tests to build up my knowledge of biology? I have unused accounts for Kaplan, EK, and PR, so there is a plethora of tests I can use for sure. How much I can trust these self-assessments? I was expecting to totally bomb the biology assessment because I never took a semester of it. Thank you for all your advices.
