I'm not sure if this is a dumb question or not but do I still need to worry about bringing an analog watch to the September LSAT? The digital test format has a timer similar to the beta digital tester on 7sage, correct?

I just completed all of the core curriculum and started taking timed practice tests. Throughout the core curriculum I rarely got individual questions/problem sets wrong, but as soon as I try to take a practice test, I panic and everything seems a lot more difficult. Is this something that others have experienced and that just gets better with taking more full practice tests or is it indicative that I have some sort of gap in my base knowledge (aka should I focus on core curriculum material or hope that I get better with just taking more practice tests and increasing my endurance)?
