I need advice.

Hello! I'm fairly new to the game (~140h on PC and around 400h on console).I used to play cs (Across all accounts ~3k h) and I know every single call-out on cs but not on r6.The way I learned and still learn callouts on games like this is by my teammates giving info and me dying because idk where the fuck that place is and then I remember it and learn it so for the future I know.Jere comes the problem I'm level 51 I think atm I just started playing ranked and it's full of cheaters so I wanted to go to faceit because I heard there is faceit for r6 as well.Bit for all the 140h of me playing I haven't heard even the voice of a single teammate.So I know little to none callous in the game.Is their a way to effectively learn them without using third party software like minimaps.Maybe a guide or a vid.I will be so grateful for your help.
