I ordered a pre-made  PC board and i think i burned off the copper that surrounds the hole when Im soldering the resistors.  it looks lke there is a burn mark and the copper trace from one part to the next looks burnt off.  Is there any chance of fixing this or am i screwed?

try cleaning it with some rubbing alcohol to see i f you really did burn it. if you did you can always use a piece of wire you connect that point to the next.

You can usually cobble together a connection of some sort. It wont look pretty but should work.

It is certainly possible to tear, burn, damage a trace or eyelet.

Here's the fix, bend a small loop at one end of a bit of cutoff resistor lead, loop over the component lead and run the new lead along the trace and solder it all down. Which all requires skills. If you lost this trace out of the many hundreds you get right, but just had bad luck or a bad day, then you should be able to fix it. If you've got no skills then you might ask someone who does.

I don't think you 'burned' off the circular bit around the hole, I think you overheated it (soldering iron on it for too long, probably trying to solder to a tarnished resistor leg or something) and the thing just fell off the board.
If the board only has tracks on one side, then just leave the resistor there, and solder one or more wires from the resistor leg, going to whatever points the damaged trace went to.
Rough? yes. Will work? Almost certainly.
