General tips: Practice aim & movement
(TIP: Don't go AWP only on Deathmatch but practice pistols, rifles and smg's as well!)
Expect your teammates to be worse than you so PLAY SAFE and clutch rounds if needed!
Don't peek/ push after the bomb has been planted
Don't rush the T-side on CT-side
DON'T BUY AWP IF YOU CAN'T USE IT PROPERLY
DON'T FORCE BUY EVERY ROUND
NEVER BUY AUTOSNIPER ON T-SIDE
COMMUNICATE WITH UR TEAMMATES! Seriously I have met so many teammates that just refused to talk even in higher ranks!
USE A GOOD HEADSET! hearing footsteps is essential for locating enemies!
DON'T BLINDLY TRUST TEAMMATES' CALLS USE UR EARS AS WELL!
MUST KNOW TIPS: Use the "looking for feature" instead of Solo Queue
if someone in your party has a red trust factor LEAVE QUICKLY before getting a match because either he's a cheater, a griefer or a noob! Also you risk getting queued against cheaters!
if someone in your party has a lot of hours / medals but a low rank leave the lobby before getting a match since this guy will most likely just ♥♥♥♥ around instead of trying
if someone in your party has a new account leave the lobby before getting a match since it most likely is a smurf or a noob and in both cases will give you a hard time
Add teammates that played well to your friend list and play more with them! This alone helps a lot!
Conclusion That were all my tips!
Thanks for visiting my guide!
