I haven’t been pre-studying Tobira vocab (even though I probably should), but have been using a 2k/6k deck since early this year (currently about half way). I have my deck set up so that the front shows the word in kanji, plays audio, and shows a context sentence – and the back also shows the definitions and the sentence translation.
The audio on the front lets me not worry about not knowing how to read the kanji yet (and when it comes up in WK I already know it).
I added the sentence on the front after finishing the first 2000 words, because some of the same words came back with new additional meanings – so I need context to give the right answer!
That combined with my current WK level makes reading the texts relatively comfortable for me so far – especially compared to some native materials But I do still look up words sometimes, and long sentences still trip me up so I usually need to read those a few times to make sure I’ve understood properly!
Bunpro shows me I’ve already studied many of the Tobira grammar points from about the first 7 chapters and some after that, but I’m generally bad at grammar so am using this book to go through all the points in a chapter anyway!
Quite enjoying this textbook, even though I have to be honest with myself and stop pretending I want to do the exercises (I don’t)
