I was able to get in a somewhat suboptimal amount of practice today. I did the Div 2 contest but struggled a bit due to problem C (which was actually my first interactive), but other than that, I only did 1 problem. I intend to do more practice than that each day and will try to make as much time as possible for CP practice since I am a university freshman right now as well, which gives a bit less leeway timewise.

With that out of the way though, the problems from today demonstrate that I require greater mathematical thinking involved in my solution process rather than just relying on intuitive ideas and proof by AC.
