what is the most coins you ever got in one day?
my record is 159
Truthfully, I've never noticed. But dividing the weekly total by seven, I seem to average about 300 / day. Whenever I have a spare moment – e.g., waiting for an appointment – I use my mobile device to do a few lessons. These 'stolen moments" of practice, in addition to dedicated study time at home, add up.
On the obverse side of the coin, it seems to take a huge number of repetitions for me to master some of the more sublime elements of German syntax.
