Wordly wise is available through online bookstores or sometimes locally at Barnes and Noble. However, the higher levels might be hard to find. The publisher is at
www.epsbooks.com for direct ordering. The top three levels are levels 7, 8 and 9. (don't bother purchasing the answer keys or tests) (get someone to check it for you or do it yourself) It look likes they're about $12.20 for each level. My daughter never got beyond level eight and she got 700 on the CR. I still have the level nine here. The format is 30 lessons of about 17 words each lesson. They average 500 words per book or level. It's pretty intense--but if you can add 2,000 words to your vocabulary that's significant. (that would be doing 4 levels) You learn the exact meaning of the words as you do the workbooks.
A lot of the local private schools incorporate Wordly Wise into the English curriculum. The new Wordly Wise 3000 books have more writing sentences for the exercises which probably appeals more to teachers.
I like the original Wordly Wise --seems more efficient to do it on your own, and there isn't a lot of busy work.
For the reading you really need to get beyond the small amount they assign in high school- I would get some of the Norton Anthologies cheap at thrift stores. British Lit or American Lit is always good for vocabulary. Write your new words on your bookmark and look them up at the end of each stopping point. Joseph Conrad also comes to mind for interesting vocabulary. If you like the author or story- then go to the library and get more by that person, or read the whole book.
If your library has access to the Teaching Company lectures via CD or DVD, pick some you like, listen to the lectures and read the books. They have many different literary themes depending on what you like- Mythology is excellent, and they have some from different eras. (these are highly rated college professors teaching these subjects if you're not familiar with them) The website posts reviews of the different courses----www.teach12.com In the back of each course there is a bibliography with even more books that you can look up!
Also reading a lot of history books or cultural geography will help you with vocabulary also. (go to thrift stores or university bookstores for the sale tables where things are discontinued and usually only about $3!) I find it cheaper than library overdue fines. Both of my kids usually read one of those rolling file carts filled with books every week. I won't say they choose the best literature, but I guess it helps at some point. My older d. said some of the AFA classes had hundreds of pages assigned a day to read, and it still wasn't easy for her, even with all her reading and vocabulary and Latin background. HTH
