Streaming my Informatics Training (ThemeCPs)
By pwned, 4 weeks ago, In English

Hey everyone, I'll be streaming my informatics training on my PHCuber YouTube channel! Here, I'll practice using ThemeCPs, which are two-hour mock contests with four problems. I've done many such practice contests in the past, and I hope that sharing my problem-solving method from a first-person perspective could benefit your competitive programming journey!

My ninth stream (held last 5/3/24) can be seen here so that you know what you're expecting: https://www.youtube.com/watch?v=SnpGzwCJbWI&ab_channel=PHCuber

I'll be streaming as time permits, mainly in the evening for GMT+8 (China / Philippine time), which is around noon / early afternoon in GMT.

Once again, I hope you enjoy my streams and find them beneficial! I've noticed a lack of yellow-rated coders on YouTube, and I hope to fill that gap! Perhaps I'll make a blog in the future detailing what ThemeCP is and how it can supplement your informatics training.

See you in my future streams! Don't forget to like and subscribe so you don't miss any of them ^^

      I first choose a random problem of the hardest topic, then I find a valid tag (that doesn't give spoilers) from that problem. I then find three easier problems of the same tag!

      The ratings are fixed in advanced by the ThemeCP mechanism.

          I made this doc on ThemeCP that goes into detail!

            I have a question: what is the formula you use to calculate performance?

              Hi! It'd probably be more instructive if you check out the formula for yourself.

              https://docs.google.com/spreadsheets/d/1gdD-syEpfy10Vz1f5UAm5eKiV_UAEdG-C4jrouN57bs/edit#gid=2025724801

              it's just here! you can copy paste it ^^

                Strange, it shows an error when I copy-paste it (I used the same rows/columns as you)

                  Oh that’s unfortunate :/

                  Do you mind elaborating? I tried copy pasting the entire sheet and it works just fine for me.

                  It says "Error, not being able to parse formula".

                  Ohh okay, I think I see your problem. Perhaps you can “make a copy”. I tried to just copy paste, and the conditional formatting had a problem after.

                  I’m unable to recreate your issue though

          I try to make connections between problems -- there may be repetitive ideas within a topic, and I hope to recognize these themes!

    I’l go more into detail some time soon! Right now, I’m still testing which method works best, and it’s still in “beta”.
