Any advice for NEW L3ers

So many of us will be moving from L2 to L3 forums. Any tips for L3? Comparison to L2? Time to study? etc. etc. Any input would be really appreciated. If you add your background and how you did on L1 and L2, and what you used to study, that would be great.

ok I had a few drinks, not sure how this got posted in L2

on the second thought, now you know there is such forum on L3
