Got To Level 11 the Forgot about WK. Start over or catchup?

The problem with having a big review pile in my experience is that apprentice items can get ‘lost’ in there, so I’d recommend using a userscript like reorder omega to single them out.
Say you were going to do 50 reviews today anyway, dedicating like 25 to just apprentice items will help push them up through the SRS stages, reducing your workload.
