I failed the Network Exam today!!!

I took the Network + exam today, and failed!!! ?The teacher gave the class a Transcender test to study from (v. 2.0 from 2/28/02( … I studied the transcender and PDF.file, with the 323 questions, and failed by 100 points.
But, the actual test was very diferent from the actual study guide!!! I’m so disappointed!!
Can anyone give me some advice, what should I do?!

Thank you!!

A desperate student!
