So, I signed up for my subject tests as soon as I could and I am retaking my physics and math. Along with those, I decided I would take a third test. Looking at the list, I chose Bio/E. After looking at practice tests, I am not nearly prepared for the test. Can I switch the test I take the day of? What one would you suggest?
