@skantmanjp, i reckon if u really want review materials, u have the best tool, and that is internet, that's what i did when i reviewed for the exam. trust me u can find almost everything, but the best materials i could recommend u is Kaplan 2009-2010 and Cambridge Volumes 1-7. U can all get this from the net, just google those.
With the writing, after the exam i thought i messed up as i run out of words with the essay thus, i added one sentece each paragraph on the last minute, but i was able to get a score of 8. With the pencil thing, i recommend to use a technical pencil (those used by architects and engineers). this was what i used. U can buy a cheaper one. goodluck sa exam!
FYI. ur words should not be less than 250 words and as much as possible limit it to 275.
