Hey guyz;

I stay in dubai and I want to learn the guitar in my summer vacation. Guitar lessons are expensive here so i turned towards the net for help. I have an acoustic guitar. I can read the tabs easily but while playing them on the guitar I can't move my fingers swiftly, I have to always count the tabs then play. I cannot also remember the song tabs by heart, I have to always look at the tabs and play.
Can anyone give me some tips please?
I want to perform in my school after summer vacations
thnx n regardz
