I actually passed on the fifth time, and i got 8 minors on the fifth test and 2 major 9 minors on the fourth one so my advice is that there is no advice, the test is basically a lottery, maybe you’ll do something slightly wrong and they’ll fail, maybe you’ll do well or maybe they’ll overlook a fault you made. For me the examiner on the fifth test basically just felt sorry for me and gave me the benefit of the doubt (I changed lanes and forgot to look before) so yeah you never know what will happen.
Edit: just realised he’s probably done his test by now lol
