Tab provided by tTabs

This is my first tab so I hope u all like it. 
The previus version of this that I saw had some errors, 
( good job though ) and from wat me and my teacher could tell this is how it goes.

h=hammer on
p=pull off
~=hold note
^=bend

G-----------5---7-9-5h7p----5-------------------------|x3
D-----567-----7----------7-7--7-567-------------------|
A---7-----7--------------------------5-7---5----------|
E----------------------------------------8---5--------|

And this is the so called "Impossible part" ( altho there r different names ).
You mostly hear the guitar but when you listen to the bass you'll hear him change it up.

G--------------------------------------------|----------------5---7-9-5h7p----5---------------------|
D----------5--------------5^------------5----|----------567-----7----------7-7--7-567---------------|
A----567-----7----567-5-----7----567------7--|--567-567-----7--------------------------5-7---5------|
E--7-----7------7-------7------7------7------|7--------------------------------------------8---5----|

These parts are right from what I can tell.
