This is a guide to get from 1-11 pretty fast.
What you need:
1.Prophecies Campaign
2.Nightfall Campaign (Recommended but not needed)
This way of leveling is much easier I think if you have the Nightfall but you do not need it to complete the leveling.
What you want to do is get a run to Lion's Arch from Ascolon or from Kamadan, Jewel of Istan. To get a run from Kamadan you first need to get a run to Consulate Docks with you can normally get in any American district and then when you get to the docks you need to get a run to LA with normally you can find very fast. (Because i do them all of the time)
If you don't have Nightfall you just need to get a run from Ascolon to LA with you could get from Somebody in the city or Guild Member/Alliance Member.
Anyway when you get there you need to walk over to D'Alessio Seaboard witch you should be able to just get a few Henchmen and run by the mobs. When you get there you need to go to a district that has no one it it.(This is imperative) Because when you are the first one to zone into the outpost mobs start to run at the gate go over to the gate and you will get exp for the guards killing the monsters. All you have to do is zone between the districts and the first wave will always give you exp.
Starting at level 3 you get about 250 exp per kill and there are like 8-10 in the first wave of monsters. You can do this after level 11 but the exp gets really low so i would just move somewhere else to get the last part of your level it takes for me about 20min maby to get from 3-10.
Why I said that I Recommended Nightfall campaign is that you can get a run from Kamadan to LA really fast.
I don't Remember where I originally learned this, but I did write this guide.
This is a Picture of Where you need to stand.

This should start you on the right way if you are going for survivor.
Well Have Fun!!!
