So I posted this super duper long ago in the comments of another discussion of mine, but I think I ought to make an entirely new discussion for this bombshell. You can skip the last 12 levels from 48 all the way to 60!
Many of you who've come that far know that the last few levels are disgustingly, painstakingly long. Now, why is that? Simple! Every level, you earn less and less experience for both blocks placed/mined and blocks crafted.
However, you will always earn the same experience for completing quests! That brings me to my strategy.
I've discovered that if you save every quest until reaching level 48, including the Quest Pack, you can start then start completing the quests and by the time you're done or nearing completion, you should hit level 60.
NOTES: I haven't tested it from level 47 but I just wouldn't risk it since that'd leave you with the hardest level possible to have to grind through. I also am pretty sure you can still hit 60 if you'd done some of the minor quests by accident (entering certain mines and/or the Cubic Learning Center), but try and save any and all quests you can if you decide to go this route.
Have fun leveling, you guys!
