You cannot be power-leveling when you aren't using GC books which gives you an additional 50% exp bonus up to 20K/40K on EVERYTHING you make.

Leves is one approach, but personally, I rather make unchecked items listed in the crafting log, and get the log bonus. Goal is aim for high HQ % which adds additional exp bonus, 250%-300% with 1K-1.5K per item are typical when you are trying to level low level classes.
