Set problems in GMAT

[GmatKiss]

Hi,

Both GMATPrep and OG Guide does not have any problem involving more than 2 sets.
They are limited to set A and B with union, intersection rules.

So, is there anything which we would need to know more on!? (3 sets and more)
Please help.

TIA,
GK

I have seen 3 set problems appear on the real GMAT and also on several mocks I have taken. There arent many 700+ problems you could ask involving only 2 sets, while more than 3 sets has never been asked, I strongly recommend you practice problems involving 3 sets. The underlying concepts are the same in sets and beyond a point it does not matter how many sets are there. But you need to practice until you are comfortable till that
