My ds switched over this January to LP english 8 and history. They are different then what my ds is use too. As far as the history we got rid of that asap, but we used the English. The vocabulary is mostly technical jargon, which on some level it is good, but he doesn't really seem to grasp it as wen we used Wordly wise. The student defnes the word, but really doesn't really use them in content. The spelling seem to be off beaten words and just look like busy work. With that said the material itself is to the point and informative. It spent sections on origins of words,which my ds liked. It is laid out different than other curricula. It is written in units, which is nice if you want to skip a unit. The LP representative told me that it would cause a problem and so far it hasn't. Though it is packed with information, I am concerned how much my ds will retain after the year is over.
PS If you do decide to try it, I have to agree with the others the AO site will harass you if you do it through them.
