Guitar Pull Off Exercises

How can I learn guitar fast?
I am kinda new to guitar, but I can play some songs. I just can not read music or do something like pull offs, hammer-on, or play fast at all. Is there any way I could learn how to do those (like exercise) easily without classes guitar or buy expensive things.
Learning to read Tab: the top line of the guide is the sequence of the bottom of the guitar's bottom line is the guide sequence top of the guitar (lowest score) and the numbers on the tabs ate the numbers of the frets you need to put your fingers as number 1 in a guide is the next fret the head of the guitar, then you just play the notes in the order they enter the guide and you can play almost any song! good luck;] x
