Lego / Security,
Any examples of the algebra/number-thoery problems. While conceptually not hard, I find these real difficult to get right under time pressure. I am sure many other people feel the same way...

Yes, from my experience, this is pretty much the standard of prob/comb/perm Qs on the GMAT. No matter which range your in, it wont get more difficult than this. Don't work too much on these questions, you'll waste valuable time that can be used to enhance other skills for the GMAT. This is pretty much as hard as it gets.
