[HELP] needed please about 2 things

First of all in the CT in cheat engine what mean 1 EXP 2 EXP and 3 EXP is it change your ammount of experience or whatever please tell me? and second is there any place that you can get aimbot?

umm for the exp1 and 2 and 3 is the same thing u change 1 and allchanges,and its used to get unlocked items but u actually arent that lvl,and for the aimbot use search if there aint there aint.and dun ask..

I don't understand about the experience like after i tick one what I do?

first change it to any value u want a big value like 99999 then u tick one and it ticks all of them then u go to shop and u see ur rank have changed the higher the value the higher the rank.then u can buy the unlock stuff..
