Just remember that getting 90% right every time doesn’t mean you’re bad at 10% of your review items.
If you have 1,000 items to review (eek!) and get 90% right, that means you’ll see 100 again soon…
…but when you see than 100, you get 90% of them right, meaning you’ll see that last 10 right away…
…and when you do, you’ll get 9 of those right, leaving you with only one single, solitary leech to squish. (And next time, you’ll have a 90% chance of getting it right!)
I mean, that’s just math. 私は数学が好きです。
