It looks like I have to wait 2 hours before the next lesson is unlocked. I can appreciate the benefit of SRS, but the 5 and 10 minute intervals for Hiragana and Katakana seemed to work really well for me. At the very least having the site tune the lesson frequency based upon success rate would be nice.
I am on winter break for another 2 weeks, so would like to get as much studying in as possible while I can do it 8+ hours a day.
If this is something that exists and is locked behind a paywall then please disregard (I wanted to try the three free lessons before buying, I’m weighing between this and kanjidamage atm)! Thanks for the help!
