Ive had several mock tests, but in my recent three tests i failed because of just major faults. Some of them include: i didnt recognise the mini roundabout soon enough and had to break abruptly(there was lots of trees and bushes). I was approaching a crossroad and i meant to turn right, but I signalled just before a side road. To overcome these errors, i figured I should a) always read the road signs b) look ahead c) calm down and not lose concentration.
I also feel like I don't know the hierarchy of errors. For example I think not looking in my mirrors before and after overtaking parked car is just as important as constantly reading signs.
Any advice? Anyone been through something similar?
