I agree. 2000 players are actually pretty bad, and 2500s are pretty good. It won't happen in a month.
How to go from 2000 to 2500 in a month?

Not true. My coach Borislav Ivanov taught me from 1500 to 2500 in 3 months.

All this is the advertisement of a GM that promises impossible things.

You noobies, of course it can happen in a month. You just have to change the code of the page for it to say 2500.

you could try increasing your rating by about 125 points a week, which works out at about 18 points a day, which is only about a point per hour. easily achieveable with the right motivation surely.
its possible in K-40.You are in great form,Play some open like Aeroflot open and beat all the GMS,IMS

It's not possible in a month. You maybe need to be 2000+ to understand just how far above that level GMs truly are. If some kid went from 2080 to 2500 in a short space of time then he was vastly underrated and it was just a matter of rating-correction.
I think FM Tor Fredrik Kaasen made a leap from ca 1900 to 2400 in a few months autumn 2016. He was a top two 14 year old in Norway at ca 2300, and made some really bad tournaments, dropped down to ca 1900, and then he made some fantastic tournaments, including Oslo Chess Festival where he earned an IM norm. Tor Fredrik fell so dramatically in rating the summer of 2016 that he was invited to play for the Norway Gnomes in Pro Chess League. In Pro Chess League there is an average ratinglimit for the teams, which means that underrated strong players are very good to have. They can drop the ratingaverage, without dropping must playing strenght. 2500 is a lot more than 2400, and the leap from 2400 to 2500 can take decades or never happen. To climb fast from 2000 to 2500, you first have to achieve ca 2600 strenght, and that is doable in twelve years starting at the age of 6 if you are very talented and have parents that can hire GM-teachers. The fastest way is probably to attend NTG, a Gymnasium with chess-class lead by GM Simen Agdestein. GM Aryan Tari did that, but he never dropped to 2000 after reaching masterstrenght.

The difference in calculation gives, at best, 10% contribution to the level difference. What really makes GMs GMs is their incredible experience, knowledge and understanding of positional play. You can't get those things in a month, even if you genetically modify yourself to not need sleep, food and water and just dedicate every single second of that month to chess.
