Lola,
Guessed slightly more than 25%, and I did skim through Schweser ethics and quant. However, the point is that L2, even though there is no GIPS, is going to take enormous amount of effort to pass. Don't let the 42% deceive you, because the test was only 50 questions long (10 sets of 5 questions). I was looking at an actual Schweser L2 exam that I didn't even bother with after reading the first item set.
