As much as the prospect of speeding through Wanikani might be enticing, might I suggest something different.
Since your free time is temporary until your classes start back up again, why not use this opportunity to establish a consistent WK habit instead of speeding through WK during the break. I mention this because I get a bad feeling that once your classes start up again, you won’t have all the free time you had before, you’ll get overwhelmed with the reviews during your months “cramming” wanikani and you’ll feel discouraged, tired and drop it once they start piling up.
I’ve been working on WK for about a year. I have a full time, 40 hour job and I’ve been sticking with this routine that ensures I keep learning and I have time everyday for WK.
First, I do 10 vocab words a day. If I come across radicals, I’ll finish them along with the remaining vocab from the last level since they’re simple enough.
Then, once I come across Kanji, I do 10 a day. Usually there’s 33 kanji in a level more or less so depending on how I feel, I’ll cram the extras in the last day or take a “mini break” and only do 3 the next day.
As for reviews, I’ll do reviews as I have time. No real set schedule and this is more based on when you’re available in a day.
So you may ask “what do I do with all the rest of my time?” which is a good question. Do other, Japanese language related activities. Learn grammar through books or videos, practice reading and creating sentences with the grammar point you learn, use Bunpro if you dont like books, listen to shows in Japanese to get familiar with the language.
Point is, WK is meant to be brief periods of time in the day to remind your brain to remember words over a long period of time. All of the other points I mentioned take much more time and comprehension. Of course, depending on where you are in grammar will have you do different things that may or may not be what I listed above. They’re just examples.
To this end, I think this is the best of both worlds where you’re being efficient with your time and attacking Japanese from two different directions (vocab and exposure).
