The 920-433 exam contains 85 - 90 questions and gives you 90 minutes to complete them. That works out to a brisk pace, so you cannot afford to stall on a single tricky item — flag it, move on, and circle back if time allows. Before exam day, run at least two timed mock sessions with the TestKingFree desktop or online test engine; practicing against a real clock turns the official time limit into a comfortable rhythm instead of a source of panic.

To pass the 920-433 exam you need a score of 70% - 75%, and the official registration fee is $125 - $150 USD.
