When we’ve finished Level 3, I’ll be getting to work on scripting (or finding someone to script for me, if we have the spare cash by then!) a dialogue-driven trip through the most common 4000 words - in which we’ll attempt to introduce blocks of new vocabulary with enough different instances of each new piece of vocab to give the listener plenty of context to understand them - and they’ll come with a list of the new words, a full transcript, and a full translation.
They’ll be accelerated, too - so it will be important to have gone through the accelerated listening exercises from Levels 1, 2 and 3 - and I suspect that huge passive exposure to the most common words will be a very helpful tool for bulk acquisition of vocab
