ok, i consider this a challenge. at first glance i feel comfortable with 67 of them. that's a pretty poor showing........ admittedly, it has been a few years since i graduated from high school.......but hey, it's never too late, eh?
i might just stick post-it notes all over the flat - only allowing myself to remove them once i can spell and define them without hesitation. works for learning a foreign language, so why not do the same to learn tricky english words?
(at a more advanced stage of the challenge: try to use at least one of these in conversation every week. oh, people will love that! *ahem*)
