Do the pacing math before exam day: with that many items on the clock, you need a steady rhythm and the discipline to flag a hard question and move on instead of stalling. Two or three full timed sessions with the ActualCollection test engine will show you exactly what that pace feels like, so time pressure stops being a factor on the real day.
To pass the Microsoft TS: Microsoft .NET Framework 3.5 C Windows Communication Foundation exam you need 700 (on a 1000 scale), and the official registration fee is USD 150.
