When's My Best Work?

So I participated in personal experiment see when and where is my best work. I attempted 3 simultaneous mathematic equations and wrote 2 sentences about a YouTube video; I done this for 2 days at 4am, midday, 4pm and midnight.

4am

      At this time of the day I would make many mistakes during the mathematical equations where I would often treat one side of an equals sign but forget about the other - but I would not be able to correct myself.

      For the YouTube sentences I would struggle to get started and once I did I would get stuck fairly often on what words would work best and once I re-read later on I would notice that my vocabulary was very limited.

Midday

      At midday I would still feel a little tired and would still make common mathematical errors but I could easily see where I stumbled.

      While writing I struggled to get started but I was a lot more efficient in my vocabulary.

4pm

      I found at this time I made the best attempts and writing and solving equations, although I moved on to factorising quadratic equations where the coefficient of x^2 was more than 1. I also felt confident enough to write a lot more for the YouTube video.

Midnight

      I was completing the mathematical equations well with a little or no mistakes but I could not even start a writing assignments on one of the days.
