actually the worse the instructor the more likely u will pass,
cos if he's strict wif u then u will learn even better... that's
wat i think.. haha...
ok... i tell u how i turn into filter lane, not 100% correct but
can make it lahz... 
1) when approaching filter lane, signal left n check left blind
spot, prepare to drop gear to gear 2
2) when inside filter lane, brake a little n drop to gear 2
3) c if got pedestrian anot, if got then stop, if dun have then
proceed up a little bit.
4) then c ur right side got car anot, if dun have then u check ur
left blind spot for motorcycles b4 u move off
that's it...
1. wrong method use for looking at rear mirror .
ans: hmm.. ur wrong method for looking at rear mirror wat does it
means? tot juz use ur eyes look at the mirror every 5 - 10 sec for
a short glance?
2. wrong position of leg after release clutch.
ans: wrong position ah? where do u place ur leg? i always place
mine on the floor board near the clutch, can rest left leg oso
mahz.. LoL! 
3. weak in steering the wheel
ans: always use both hands to hold the steering wheels. hold it a
bit firm when u going to make a turn cos there will be a force
pulling ur steering. it is called power steering i think.. not that
sure wat it's called.
4. make wide turnings
ans: this depends a lot on ur judgement n control of the car, if u
always make wide turnings hor, next time at a turn, u remind urself
to turn more...
5. throwing the clutch and pressing too hard on the
accelerator
ans: throw clutch ah... haha.. u sound like me... last time i
always do that 1.. then car jerk n jerk... this 1 u have to rely on
urself liaoz, must keep reminding urself to release gently...
practise more... that's the only way.
pressing too hard on accelerator is for the lesson called Rapid
Acceleration. the way to overcome pressing too hard on the
accelerator is to have a feel of the acceleration of the car, if u
feel that the car is slowly accelerating, step a bit more. if u
feel the car is accelerating too fast, slow a bit.. this 1 u have
to depend on ur judgement.
6. car will shift to the right n can't keep e car in the middle of
the lane
ans: actually to correct this error hor, i try to steer the car to
the centre of the lane by steering the car till the driver seat is
near the centre of the lane. cos the lane is very big for the car,
so if the driver seat is near the centre of the lane, then u will
be more or less in the centre of the lane already.
ok lahz... my post super long... hope can help u...
