Customs is great for new players.
-You dont get lost that easy because its so narrow (not a lot of open areas), you can always hug the wall and progress through the map
-There are not a lot of loot spots: Well thats actually a negative for experienced players, but as a new player this actually helps you to memorize the spots
-Few possible lines of sights where you could get shot because the map is much more close quarters combat stylish (only a few long range sniper spots)
-Go for a hidden lootsstash run and try to hit a lot of them in a short amount of time.
Play it as a PMC and when you can SCAV into Interchange. Interchange is a lot harder to learn in my opinion. Try to hit tech stores (4 stores in total on the map) and get the hell out of there.
Good luck!
