Sorry im late, quick rundown on how to survive and learn. A. Look it up, use youtube, google the whole rundown. if you are new, land in small unmarked places. Try to find the correct sensitivity. Play in teams with people you know for a while they may have good tips and it will help you see the flow of battle.
The best way to learn how to play is to parachute into school. There is always a ton of people there and you will die but the intense combat will give you experience. It may get frustrating to die so frequently and quickly but trust me. If you want to learn to be good, the best way to do it is to jump in and don't be afraid to die. Learn from your mistakes.
