You can pass it the first time if you study hard and work many problems. Don't waste your time taking it if you are not prepared to really work.
Easy problems do pop up.
There is a grave danger of studying what we know well already, particularly for folks like me who have been out of schoool for two decades. Resist the temptation to focus on just one or two areas, since this will restrict your ability to pluck low-hanging fruit in other areas. No matter what anyone tells you, you can't learn it all. Pick your areas of expertise and focus on them hard. Find your strengths and hit those hard.
