Is it possible to reach 2200+ in a year?

Possibly, this is doable.
But, I would strongly suggest you concentrate on the process rather than on the final result!
I know very few people who improved by being willing to just improve. But, I know countless who improved because not only did they want to get better, but also they were enjoying the process. Would they be worried if they improved a bit less? Maybe a tiny bit, but in the end, they would still win, because they had the pleasure of studying chess. Being focused on results only isn't the best idea.
I wish you the best of luck!

Completely agree with darkhorse_98. The truly great players were those who fell in love with the process of improvement. However, I believe you can channel this to achieve your goal of 2200+ in a year. To do this, I would suggest:
1) Working a lot on tactical ability
2) Spamming games and analyzing each of those games
3) Knowing the basic plan of your openings (but not necessarily theory)

Don't spend too much time on theory, as you only have one year. Focus on the skills that will allow you to outplay your opponents out of the opening. If you have to switch to even less theoretical stuff so that you spend less time studying openings, do that. You only have a year, which means every day counts!

anything is possible.

First you need to be in the top third of every chess tournament you participate in.
Graph your tournament performances.
If it is increasing, then yes your rating will follow.
Your performance will reach the master level, way before your rating does.
You will need to win a few masters before getting the title.

Reaching 2200 and dropping to 1800 only shows a peak rating.
But it shows the potential to reach that level.
Rating stability is a stepping stone.
Learn something new and the rating will again increase.

@TitleKiller It seems that you are one of the few players who has the correct approach to opening theory, and I would say, generally speaking, one doesn't need theory at all in order to massively improve his play. Tactical awareness and some basic plan should be just enough for that 2200 target. More than that, learning opening theory it can destroy one's natural abilities.
Many years ago (in 1995) I've won my first game to a NM, it was a trap in the Sicilian, Sozin Attack variation, during that game I just couldn't remember how to finish off that trap but my opponent resigned anyway. Obviously I was so impress by my own performance that for the next five years I wanted to learn all the openings, which I eventually did, but the difference between theoretical knowledge and my tactical abilities was huge. So, I was totally confused by non theoretical lines, usually blundering everything in the middle game. Learning theory instead of understanding the game was a great mistake. I've wasted five years learning the wrong way. However, for the next year giving up theory brought me some real improvements, winning against NM on a consistent basis. Then (in 2001) I gave up chess thinking it was a boring game. LOL
Which it is.

It is obviously possible. Viable is a bit tougher a question. Depends on alot of things, age, experience, dedication, etc etc. 2200 is a kinda high goal, I am nearly there in everything but blitz because im too slow, but a tad piece of advice is that when trying to get to 2200, the sicilian defense is not your friend, just an unnessesary source of studying

And if we were all to say it is impossible...does that make it so? ;)

Every time somebody asks this question, I always think that the question itself is a strike against them (and their chances). Presumably if you're going to get to 2200 (or try anyway), you'll just do it...not ask a bunch of random goofs online what they think your chances are.

hell yeah you can do it

@NoobBatter The real question: can you get from 1500 to grandmaster in 3 months, assuming that you only get 4 hours of sleep a night?

@A_0123456 hell yeah anything is possible
