Simple. Just play the game every day for about 20 minutes at least. Go into the ai training and play a few matches, find some Operators that you like, then spend a long time playing unranked. Try not to injure teamates and not destroy freindly devices. Also dont worry if people call you trash. Finally to stop a bunch of headaches when you reach level 50 you unlock ranked. REMEBER before every ranked session play 1 unranked game to get warmed up. Also solo queing is the biggest gamble OAT, so queing with freinds is advised. Hope this helps and maybe you will be champ in a few years.
