Play the objective.

Attachment with silencer is the best *personally for me*

Choose squad that look cooperative - usually you can get the idea upon looking at the perks chosen by the squad members. Same perks = n00bs.

Camping is usually not acceptable especially when you are miles away from objective.

Don't fly heli or aircraft when you don't know how. Choose empty server to practice, not during peak time. Every vehicle spawn is too valuable to be use as practice.

And the last ; when you see team as stacking the rank on one side against your side - get out and choose another server. Its will be a rape feast and will fu­ck your kdr and spm.
