This is a common myth however driving instructors do not have quoters, if you're good enough to pass you will pass.  What you need to demonstrate is that you are safe driver, if that's the case then you will pass your test with flying colours

Stalling and regaining control of the vehicle and moving off safely should not result in a test fail. It all depends on the situation at the time and if any other road users are affected. For instance, if you pull out of a junction and stall the car and force another road user to brake sharply, this may be marked down as a serious and dangerous fault. Like many of the other faults, it often comes down to the safety of the situation.

You don’t need to use exaggerated head movements to show the examiner where you are looking, including your mirrors. Providing you are checking your mirrors effectively, the examiner will know that you are doing so. Under no circumstances should you adjust your mirrors in such a way that it forces you to move your head more than would be normally necessary.

You should be trying to maintain good progress whilst driving if it's safe to do so and you can drive up to the speed limit then do so if there are hazards or reasons to drive slower or more cautiously than this is also more acceptable and what you should be doing do not try to drive extra slow in order to give yourself time when you don't need to you do not have to stop at every single give way but you should always make sure that it is you have made sufficient observations to make sure that it is safe to emerge from any junction

Crossing your hands whilst driving is not wrong as long as you are maintaining full control of the vehicle at all times. Rotating your hands around the wheel was acceptable or you can use a pull push technique however make sure that you don't end up with both hands on one sided steering wheel or steer as if your hands are glued to the wheel.

There's no special day or time to help you to pass your test. Monday or Friday makes no difference in the morning the afternoon no difference.  If you personally have a time of day that you function better, then by all means aim to take your test then if you feel that would help you relax more.  However, you should be comfortable and have practiced driving in a variety of conditions and times

Being stuck in traffic is not going to shorten the amount of time you are driving on your test. If you do get stuck in heavy traffic, you will still have to continue the test route

Going the wrong way or missing a turn is not an automatic fail on your test, providing you take the turn safely. You need to demonstrate good planning skills but providing you are not doing anything unsafe at the last second or continually going the wrong way, there should be no problem

Whilst you should be avoiding clipping the curb it’s not always going to result in a fail. If you lightly touch the curb on a manoeuvre whilst making full observations and the examiner deems the situation safe you may not get a serious fault. Again, it all comes down to if the situation is safe. If you are mounting the pavement and pedestrians are scattering, you can assume you’d fail. If you a hitting cubs on every junction you can assume the same, but one little back wheel clip as you exit a junction isn’t the end of the world.
