if the question seems easy, it is easy. that is the catch.
They have some very easy questions giving you lot of points.
You can go easily to 60%-70% without thinking to much...
70% is as good a 0% and there are plenty of difficult and tricky questions out there for the remaining 30%
when you are finished with your paper, just resist the temptation to correct...and you should score 75% at least.

d) As long as the amount of time available.
