Here is a blog by me on chess books, Check them out!

also analyze all the games that you play here! And learn from the mistakes. Ensure that you do not repeat them in your future games.

Also the amount of rating you gain depends on how you practice!

If you practice hard and follow the tips I just gave you your chess.com rating will increase to at least 1700 by July 2020

Hey! That's awesome improvement  I started a year ago, at 600, and it took me basically the same amount of time as you to get to 850  Keep it up!

It's bit faster than me, though I don't play each day. I think it's fine.

Thanks. I got some of the books u recommended. Hopefully, it helps

I am 18 BTW. Thanks for the suggestion. I do tactics everyday and have been improving but I still blunder a lot during game and that's what I am trying to put a stop to.

From what I gathered. Openings doesn't really matter at my level. I stopped freaking out about it when I read it somewhere..still, I learnt Sicilian, London, Italian, Ruy Lopez and few others

would you like some free coaching? (mind you it would not be regular)

Yesss.....I would appreciate that

hey thats not bad ... it took me 7 years to get to this rating 

Astounding improvement. Most of us have to do something drastic to bump up the rating 400 points, like get a brain transplant. For me, I quit drinking, then watched my blitz rating climb about 300 points. Pretty much a brain transplant.
