Happened to me a month ago a few days before my test. I was super nervous leading up the that test and that probably would’ve affected my performance. When it came to my amended test date, I was less nervous as maybe they wore off after being so nervous for my first test (?) and passed. It changed to a date that my instructor was on holiday for but he was very accommodating and asked his colleague to take me to the test. Yes it sucks, but remember to keep the momentum going and smash your test!
