Each person has their own reason for engaging a school or
private instructor. It's juz a matter of peference and cost.
Personally, used to be with the school and I feel that although you
may not have the same instructor throughout the duration of your
lessons, what you learn tend to be in a more structured format and
you are made to refine your driving skills till you passed each
stage of the course. In that sense, most students seldom accumulate
points within the circuit itself. Most make mistakes due to
situations when they are out on the road.
Wearing short skirts and sexy clothings wont make it even easier,
it all boils down to how's your performance on the acutal day
itself. Some may pass on the 1st attempt and others after numerous
attempts but as they are issued wif the same license, I dont see
the reason that one is better than the other.
The best drivers are the ones that start their journey and arrive
home safely. No matter how good you think you are, your life is juz
hanging by a thread when u r on the roads, a moments folly may
render u immobile for the rest of your life or u would end up in a
6' x 4'. Drive safe and enjoy the ride.
