Good luck yaar.Dont be nervous,and dont be all sweaty and shaky.InshaAllah it'll be fine
My sis is taking lessons and she'll give her test in December.
Two VERY important things:
1.Keep checking the mirrors and dont just glance towards it,turn your head slightly,so that the examiner can see
2.If the examiner asks you to go in a wrong way,ie,drive through one way road in opposite direction or go against ANY kind of traffic rules or any kind of signs.DO NOT obey.Just politely say,"Thats against the rules,sir."
He'll probably say,"Oh its okay,I'm with you".DO NOT give in.Its their trick.
Then ask him,"where should I go next?"so as to let him know that you are totally reluctant to do it.
This is because they test you whether you break the rules easily;obey stuff even if its wrong...etc
Those two are my dad's tips to my sister.Hope they work!
