Iam using the tactical trainer I have trained 6-7 hours total(effective time)

I think its a great tool.

At first I got angry when things did wrong its a hard learning tools no misstakes or second chanses its good in the end.

Now I am curious how good I achieve. I have improved from after 2 hours I had I think 1800 just above 1900 maybee.

Now I have passed 2100 and 2200 and will pass 2300 very soon.

How good is this? and what limits are it 3000 or more?

I recommend that you take a look at the Tactics Trainer rating graph at http://www.chess.com/tactics/players.html as that will give you a good gauge of where you are compared to others.
