on the web, there are results lurking (I suppose some people post their result table on their blogs or something)
and I’ve stumbled upon some people like failing 1, 2 or even 3 (!!) sections but virtually every other section was >70% so I guess that compensated
That is true. The topics that I had less than 70% were the smaller topics and I only failed one topic (quants) that wasn’t worth much. Tho really you shouldn’t be banking on this information and hope you pass.
