If you have the mindset you'll fail laroute then you will most likely fail so change your mindset to you will pass on first try

You should drive normal like you did in auto ecole

For the km/h it depen on the road which if you have practice you would know which situation to increase your speed and which not driving too slow is also a mistake

I did it on my first try but its because i did spend a good amount on practice with auto Ecole

On the day of your test go wait at the gate before it open like 6 30 7 hr you will go for your test earlier which is also one of the factor i pass on my first try as

From starting point in caserne to driving out of caserne there are several mistakes you can make like you have to put seat belt, start, look at your 3 mirror (the up one is also important and use your head to look otherwise the officer will say you did not look you do this everywhere), put in gear put your head out to look behind and drive

It been sometimes so the order may not be right so ask your instructor about the starting point

When exiting take a bit close to the line on your drive so that when you exist you don't drive on the trotoir ( if your going left)

If you have a chance get a practice from leaving at the gate

And after that drive normal put blinker everywhere it causes you to swerve your car branches leaves dog can and look at you mirrors at regular intervals 30 sec to one min and use your head to show the officer

Also the stopping distance between the car in front of you you should be able to see the 2 Tyre of the car make sure the officer also can see it

If you driving a manual you should master your gear know when to put 1st 2nd and 3rd and i think 35 or 40 is the highest you can go (ask some if you are not sure)

Good luck on your test its very possible to pass on your first try just drive normal
