Thank you for your response.

I guess you guys will need to educate your employees because at no time did they tell me the possibility existed that I could re-take the test.

The CD issued by Al Khebra is quite useful.  I wish more people paid attention to the principles.  One thing you may want to do is have the relevant person amend the Round-a-bout (U-turn) section of your cd.  A driving school should never distribute a cd to "learner drivers" demonstrating the car mounting the curb and spinning while going around a round-about.  I'm now apprehensive about the training I will receive but hopeful the instruction manual and cd are not indicative of the actual instruction process.  Thankfully, I was taught the rules of the road elsewhere.
