Question: how to know how much xp you have on fortnite?
Answer: The best way to level up in Fortnite is to have the Battle Pass at level 100 so that you have the 120% EXP boost and the 40% Friends EXP Boost. Then you'll need to play Squads with 4 others who also have maxed out their Battle Pass so you all have the 40% EXP Boost.
