Welcome to the 20’s.
As many have found out, this is about the level where you can’t easily sustain clearing your lesson queue every time it comes up. Ask me how I know.
I’ve found the following to be extremely helpful in keeping up with WK:
- Keep Apprentice items around 100
- Keep Guru items around 500
- On a new level, do 20 lessons per day until the queue is cleared. You should unlock the next batches every 4-5 days.
- When you start a new batch, do 20 lessons per day until that batch is done.
That should give you about 10-15 days per level and seems to be a manageable pace.
