Level doesn't determine your play time.
You can boost, pretty lame but you can, get 80k++++ exp per round, every round.
Or you can play legit search and destroy matches, along with some other high exp game types.
Without Challenges I average around;
10-20k exp per search and destroy game.
5-10k exp per free for all game.
5-10 exp per TDM game.
I play mainly search and destroy, and after doing several challenges (such as weapon veterans (unlocked after 1st prestige) you can get 20k exp, 10k for veteran, and 10k for marksman VIII ) And the most I've gotten in a single legit match is 67k. By getting UMP45 marksman 8, UMP veteran 2, marathon Pro 5, hardline pro 6, and ninja pro 5 all in the same game. Rest of the points came from headshots, longshots, buzzkills.
