every site has a different rating scale I past 1500 in 2 yrs on another site. I jumped to 1700+ after coming to Chess.com in 6 months.
How long did it take you to cross 1500?

I'm not sure. Probably about 3 years and then I just kept going until I broke 1660 last month and then dropped over a hundred and fifty points.

I hv been playing chess since my school days. When i joined chess.com last year, it was already 1500 though it sometimes fluctuated badly..
When I was young I was considered a real talent in my town. My first OTB rating ever was 1400 already. I broke 1600 in the same year. Somehow I lost motivation though so I only ended up at FM level.

Dude - you're 1457 in blitz right NOW.
You can probably hit 1500 immediately just by getting 2 days of good rest and then playing your hardest in an uninterrupted setting.
I routinely fluctuate between 1400-1600 based upon my rest level.

Well first of all we must point out that there are many underrated-sandbaggers players that stay on purpose around 1150-1350 level. But they are higher rated than that. Probably around 1700.
When i first joined i was about 1300 rated blitz and quickly made into 1500+ thanks to my speed in 3/0 pool and the fact that you gain more points at beginning. Maybe a week or so. I already had experience some 5-10 years ago on other servers. Played over a year on other places. Here Players were extremely slow and bad at endings. But when i played on another account (its deleted) that were around 1100 rated i played players rated 1150-1250 or so. Man.. at least few of them almost beated me both on position and on time. Fast and accurate moves, some were engines but many were just real skills but with their low fake rating...
It is extremely dificult for a real beginner to get high on rating ladder. Becouse he just lack experience. there are many players that are close to his rating but with thousands and thousands of games on their back. I remember (before chesscom was created) that i was skipping players with 20-30k games (on other site) they just moved too quick and knew a lot of stuff, but still they were beginners with blunders, but i skipped them becouse i was scared of them i was like a bunny to them.. i wonder why they did not improve.. Still even now many low rated players with 30k games remains with low ratings..

Do you have any source for that claim? Sounds like an excuse a low rated player would make to explain why they cannot make progress.
Not saying you use that excuse since you are obviously much stronger,

(Assuming you are asking how long it took me to reach 1500 USCF Standard or above) Starting at the moment I played in my first USCF-rated chess tourney when I had just turned 9 years old (where my first rating was 849 [P5]), it took me about 3 years to get to get above 1500. From that point, it took me a little over 5 years to get above 2000 (as well as establish a rating floor of 2000).
Crossing 1500 is actually very simple with the right knowledge. I can say that as I did it within my first year and am now at a level where I can not even understand how I was that low once. When I look at the games of lower rated players that constantly ask in the forums about openings or endgames I see so many obvious errors and their openings still suck. They need to study the right things.
Please share.
