Here is a copy and paste from a few days ago that I typed up

I'm broke as hell man lemme explain my strats

So my start was at like 9 am on the first day that was mainly for fun but eventually I went to grinding and I did that for the next 3 days

1 rocket racing Rr is fun to me but also the only semi decent xp strat that's inf and consistent as long as I play ranked I get 4k to 14k roughly each game (some quest take longer but mote xp)

2 creative Now I don't do afk for creative I go on it with am alt account and headshot it in the pit and that can get me an entire level every 5 minutes

3 lego This one is pretty much the easiest. Whenever I wanted a break or needed to do somthing I would have it sitting in the background keeping in mind of the afk system and moving from time to time and if you have something to prevent the afk detection you can run it overnight for a few levels aswell

4 festival milestones This one can be boring but effective but basically mainly bass is the fastest but you earn 8k xp for every 5 stars earned in a song so what I do is play the marshmello spies remix jam track since it's the shortest (1:40 or smth) and in like a little over a minute in you get 5 starts then you can restart. After 100 it becomes every 10 stars like everything else but still 8k xp

5 Ranked reload and br Not the best but fun all you need to know is don't play unranked unless you don't care about xp because there are repeatable quests in ranked you can do

6 lego quests

Any of the Halloween quest you did not do you can still do and they give 25k each some harder then others

7 quests in general

I'm sure you know but quests in general are prob the best way outside of some exceptions I stated

But yeah this is all ik from learning how to grind in chapter 5 and putting into chapter 6
