Congrats.
I think a lot of people on this site who are started at 1200, and immediately fall below it, have this as a goal.
Yep. I started playing chess around the start of 2015. I signed up for a chess.com account in April/May and my live rating dropped to around 800. I did a lot of casual studying and now I'm around 1255 just 4-5 months later. I hope to maintian or increase this speed of progression as I continue playing and learning.
seems like you managed to reach 1300++ within 16 months. congrats.
