Thank you, Mobbsy91.
I feel a lot better now, and I know my mock tests aren't necessarily reflective of how I can drive. I drive better than that ( a lot better, in fact) and perhaps that's why I was so disappointed.
As to the validity of the mock test, even though I'm finding them very difficult, I'd rather have them than not have them. It's not so much to see where a student is at in their driving-because, of course, the instructor should already know that. It may, however, highlight some areas where the student specifically needs help. It is more about getting the student accustomed to test conditions-having someone sitting beside you, who might not be talking, who is armed with pen and paper to judge you.
Throwing a student into a test without giving them adequate practice time in a similar environment could be, for some, throwing them into the deep end. I get that every instructor is different, but there's a huge difference between writing it out what will happen and having them actually experience it before test. Huge difference.
IDrive, so if a student specifically desired a mock test to see if they were ready for their test or just to try it out, would you refuse to do it?
