Why do some students have to fly more than minimum hours before taking their skills test?
Largely because some of us are slower to learn.
As a huge generalisation*, older brains take longer to assimilate stuff that a teenager will see demonstrated once and copy accurately. Also, older brains may have to re-learn how to learn, and learn something very different!, iyswim. Afterall, you will be working in 3 dimensions.
I understand a reasonable amount of the theory, I KNOW I should be doing x, y, or z at any particular moment BUT it doesn't mean I actually do the action either i) quickly enough, or ii) with the correct pressure on controls, or iii) on a bad day, even in the right order
OK, I am at the very beginning of the amazing journey but realistically I'll need more than min hrs to be safe, you may not.
*There are mature students on this forum who are progressing quickly and will be not much more than min hrs when they take the test so you may not need to spend too much extra.
I've loved the lessons, even when I've held my head in my hands after shutdown (once, so far!). I am fortunate to be able to afford to relish the learning even if it takes a while.
Do your research to find a good school and an instructor who suits your learning style, and as soon as covid lockdown(s) ends we can all get going!
