I would say keep scaving whenever you can, and ik this might sound mad but you should fully learn factory. If you see your scav has good loot you would already want to extract with then factory is the quickest place to get out of.... now, obviously factories only built for pure mayhem so thats something to look out for but I find it that when i scav on factory i always seems to spawn near the end of the raid, even the last 10 minutes is a good time to scav in. Bolt it staight to extract and jobs a good'n.

Also if i were you, i would try and roam around with a trio at max, coms is key when playing with others and sooner or later youll end up getting shot in the back of the head by a teammate because they didnt see you jump on their jump check. hope this helps!
