3 months - What can be achieved?

I want to give my self 3 months

Everyday

2 Hours of online chess

1 Hour of chess with another person

1 Hour Videos &  Chess Mentor

If I review my lost online games on top of this where could this get me?

Now I'm just a beginner, making many mistakes.

If I put in that kind of time and seriousness, how far could that take me?

I know this questions ahs been asked to death but I;m really looking for some ideas and thoughts on this.

Besides that, any other things I should do to become a decent player in 3 months?

The question is, what do you consider a "decent" player?

The bad news - Three months is not a lot of time. 

The good news - improvement is quicker (with the proper amount of work) at this level than at the 2000+ level.

For your rating I would say alot of improvement ! The best is coming up for you . Enjoy the rating boost, its the best part !

You will get to atleast 1275 rating and up to 1350 ! Dont give up ! I wish I would of known that... ( but if you start a losing streak, just play unrated until you get back on your game ) :)

thanks for the wonderfull insights everyone
