What’s the best way to get xp for me?

Poseidon1000

So far I have 100% act 1,2,3,4 and 5 and I have completed act 6 and 7.1 without any exploration of either. I’m about half way from level 59-60 and was wondering what’s the best way to get that last hit of xp that I need

Probably redoing act 4. I am in the same situation and that's what ive been told
