why is bro's glicko so lo 😭😭
Because they rushed through the lessons just to say: "Look at me. I completed all the lessons."
Did they get an achievement? I assume yes.
Did they learn anything? No.
I do 15min lessons x4 every day. Or more on some days. I was inspired by zen buddhistic scheduled meditation practices, I just applied it to chess lessions. I answer until I get it right. No matter how many tries it takes
Sometimes I get it right the first try, sometimes not. I just want to learn chess. Why would anyone rush learning? I do not get it. I have now done 800+ lessons. And there is still a lot to learn.
