I’m seconding being cautious with huge lesson binges. That works for a few people, but for most of us, it gets to be quickly unsustainable. Those 85 lessons are going to come back four hours later, then eight hours, then a day, then two days, then a week, then two weeks, then a month, then four months… Even if you can handle 85 reviews on top of everything else today, how about six months from now when you have potentially hundreds of other reviews in circulation?
If you want to level up faster, there are ways of doing that that are a little more sustainable in the long term. The Ultimate Guide for WK has a lot of tips for increasing your speed and building your own schedule in WK. I recommend giving this a look and aiming to do a set number of lessons a day to reach your target pace. This might seem slow at first, but it will make things a lot easier for you in the long run!
