Easiest way to Lvl up fast (my strategy

[Hero]

1. Find your Gamemode, the best modes to gain a lot of exp is Kill Confirmed and domination. if you're a search and destroy player then stick with that mode. if you get what I'm trying to say
2. CHALLENGES! especially Gun Challenges, rank up your weapon then switch off to another Gun, which means complete the marksman gun challenges 10 kills, 25 kills, 75 kills, 150 kills, 300 kills, 500 kills, 750 kills, 1000 kills, then switch to another gun and do the same, pick a gun that you are comfortable with.
3. Specialist Package, this really helps as you're playing, it even counts to the specialist challenges such as(Get assassin 10,50,100 times or other perks, which it'll give you 3500-10000 xp for completing the challenge same as the other perks) once you have 7 or 8 kills. you'll get the specialist bonus which means you'll have all perks and all proficiencies. you'll get an extra 200 XP for every 2 kills. you can also use support package to help you gain xp.
this strategy really helps me, i rank up fast and prestige every 1.5-3 days, Hope this helps you guys! Please thank me if this helps you or find this helpful
