I'm not really asking this in terms of fluency here, but rather in the interest of time. How long would it take to go through (stated in question) at least once?
I understand that it's probably more important to focus on whether or not I understand the material.
Realistically, this is more of a question asked out of curiosity.
When I say all lessons, I mean all that have been released up to the latest complete section (Intermediate).
By drills, I mean the ones that can be unlocked after reading the lessons and not the drills you can make one your own (I think) from the dictionary.
This isn't really important, so it doesn't really matter that much to me if I get an answer on this question... Though I suppose it may be important to people who would like to complete most of these lessons within a specified period of time.
