Preparation time for Level II

How many hours do you think will it take (on average) for a reasonable chance of passing this level assuming one refers to notes alone.

I read from 200-300, but mostly 300hrs from people since L2 is tougher.

I think 300h is really on the high side. level 2 is very conceptual, I’m not planning to do more than 150-200h

How many have you already put in?
