i sadly can't play because i am waaay higher rank and it wouldn't be fun for you. i am also an adult so it would be a bit odd.
however, i have a few tips for you, make sure to run deathmatches (not team deathmatches) and work on warming up before games. try to only shoot if you are at head level to avoid panic. burst firing is also a great thing to practice. doing the bots in the range can also be helpful too. there are guides out there for getting out of every rank that may be worth your time if you are serious about getting out of iron!
