I need help

Any tips on leveling faster ? I mean I get good ratio's every game but it's just so hard to level. I've been CSM2 for a 2 days now. Any tips on leveling faster or easier ?

Power Level.
Play QR with spec m32 and claymores.
Play Bombing Run, and get 150kills / 50 deaths.
or Play cabin all day like me

How does Powerlevel work ?

Basically, you get a few people you trust. Go to QR junk Flea, then you rotate. If your a human, tell the other players to infect everyone except you. Then you kill them all. then from there everyone gets a turn and in the end the xp is great
