Am I ready for my driving test?

Shanaz,

Your instructor is the best person to ask this as he's been teaching you the skills of how to drive. If he feels and that you are ready for your driving test, then you probably are. Also if you're confident enough that your driving is good and you can pass the practical test, then you should go for it. It's good to trust your own instincts.

I'm assuming your driving instructor is an honest and professional tutor who wants you to actually pass your driving test and not trying to delay you to sit for the test so that he/she can make more money out of you. This happens a lot so it's worth mentioning it.
