hey joker, the best way to level up quick in this game is to register on the
www.battlefield.com site and pull up your stats when you are playing. I suggest sticking with one class at time to unlock the important perks like increased speed, mag ammo, extra ammo, body armor and a few others before moving on to another class. when you pull up your stats there will be a section that shows what stars you'll receive for each weapon next. stars earn you 1000-5000 points when you get them so you level up quicker by earning them as fast as possible. start with either assault or medic cuz you can point **** easily by throwing out ammo boxes and med packs for people. spotting, killing people near the objectives, destroying mcomms, capturing flags, etc earn you points each time you do those things so do them as much as possible to level up.
