A few quick questions for those who have taken the test. The ETS booklet mentions numerical analysis as a possible 'additional topic'. Anyone have a good idea what topics such question(s) would cover? More practically, is there a book out there which has the necessary info contained in the first three chapters and 30 exercises? Same questions for 'algorithms,' which were also mentioned. With regards to latter, there's a classic computer science book out of MIT called Introduction to Algorithms by Cormen, Leiserson et al. Thinking about tackling first few sections of that one just to cover my bases, make sure I'm more comfortable with notation/complexity questions... thoughts?

Many thanks!
