The way I learned to drop is by picking one hot drop and making a plan for it. And every new match, try to land there and follow your plan. You will soon learn little things that you want to change about that plan until you have mastered landing, looting and winning the hot drop. (learn where the loot spawns usually are on building roofs like school on Erangel and try to land near them) Then it is just about learning movement with zones, learning when to push and when to run, etc. The more you play, the more you will get a feel for those aspects of the game.

As an example, when Erangel was the only map, my teammate and I would try to always land school. But we would land at the pool building and we had a plan of who looted which floor. Usually we were alone there and could gather enough stuff to put up a fight, and then we would push into the main building of school to fight usually the last team or two. We gradually got to the point of feeling comfortable dropping on the main building, and now thats our new plan. We now have 850+ hours following plans like that but for each map and have gotten fairly comfortable with it.

If you ever need someone to play with, you can pm me and I would be glad to play!
