Hi everybody,
everytime after level up, all the Radicals of the new level, roughly two thirds of the Kanji and some of the Vocabulary get immediately unlocked. However, the exact number of Vocabulary items that gets unlocked cannot be calculated and differs from level to level.
Below I listed for every level the number of Vocabulary items that are available as soon as you unlock the level. For anyone that wants to see which words those exactly are, I’ve attached a pdf.
Why would anybody be interested in these numbers? Imagine you’re a few days before level up. You know that the earliest you can guru any of the Kanji in the coming level will be after day 4 (on the new level). Therefore on the first 4 days of any level you can only learn the Vocabulary that got available as soon as you leveled up + the Vocabulary you hadn’t already learned from the previous level. Now imagine you are 2 days before level up and you have still 30 Vocabulary items to learn. You might think: Easy! For the next 6 days I’ll learn 5 words each. But then level up hits you with with 40 new words. The opposite case might also be true. You cram in those 30 lessons on your last two days and then level up only gives you 1 new Vocabulary word. To avoid those cases I compiled this list, so that everybody who likes a steady schedule can plan ahead.
I plan on adding the number of Kanji of the first wave (and which ones they are) in the future. I decided to already release this post, because it took me long enough and from my perspective knowing the number of available Kanji is by far not as important as the number of Vocabulary words.
One last thing: This list is not 100% correct (probably). For several reasons I had to use the vocab lists from the old WK Stats site, which are slightly outdated. There might be a few cases where the number I state is off by 1 (or more). If you notice after level up, that I did not indicate the correct number, please tell me! I would be very grateful. When you click (after level up) on Levels → The Level you’re at you can see the number of vocab items already unlocked.
I will try to update this list as regularly as possible - I’m keeping an eye on all content updates.
