My instructor told me (when I was despairing that I had a degree and post grad qualifications, but could not master driving when other ppl who I knew weren’t very bright found it really easy) that in her experience, ppl with high intelligence like doctors etc found it the most challenging bc they tended to overthink it. She was probably just trying to be kind, but her words also rang partially true as I’m notorious for this myself. I don’t just follow instructions, my brain questions everything and it leaves me anxious as I lack confidence.
Another massive obstacle was I don’t take information in by listening very well. I have to read about it and do it. One of my instructors would go on and on explaining things, giving me instructions as I drove and I found it overwhelming trying to process what they were saying while concentrating on the car itself, as well as the road and other drivers etc.
As someone mentioned before it’s about executive function among other things. I have strong ADHD traits and would ace the theory but fail practical tests. This was also down to high anxiety for tests which would throw me off when I was being closely observed for assessment. I found 2hr driving slots (soooo expensive) worked best for me but more importantly the experience of driving between times so that my lessons weren’t such a big thing as it took a while to relax into them at the start each time.
It took me a LONG time to pass despite starting at 17. I had to have frequent and prolonged breaks in between bc of lack of confidence and motivation and the sheer expense.
I know this isn’t entirely relevant to you, OP, as a single mum, and you aren’t able to rely on anyone for support to drive with you, but I just wanted to emphasise that you are not alone and it isn’t YOU. You have more obstacles to overcome that most ppl don’t have so are naturally at a disadvantage.
Have you thought of an intensive course? Sorry if I’ve missed this info in your updates. Maybe worth saving up to book a load of longer lessons with the aim of taking your test sooner. But if you pass or fail, don’t ever feel that you are a failure, just putting yourself out there is worth feeling really good about yourself that you are placing yourself outside your comfort zone for your kids - it shouldn’t be understated or underestimated .
Good luck!
