I started studying at 10 and was already tired so I should’ve started earlier. I finished the 1d motion multiple-choice questions and then started working on free-response questions. I noticably struggled; and it was concerning to see myself struggle at some, what should be, simple problems. Or, I could have been a bit brain-dead. One thing I have noticed is that I’m slow at adjusting to unfamiliar problem types — which could definitely be an obstacle to competitive problems.
