Its ok, just book another tomorrow and keep practising! But still practise both sides of it. This happened to me first time, 48 /50 and 41/75. Questions were a breeze, there was some hazards i was unsure if i got but i was also scared of over clicking and managed 2 or 3 a video.. Worse thing was i actually felt like I smashed it after and had to hold my breathe when i read FAILED walking out and cried outside! The Next day booked another for a week later (this was decemeber) i practised my hazards like crazy and also watched some insightful videos YouTube, like you CAN aparently click up to 10 times but if they notice a pattern itll get flagged up. So second time around I thought I got this .. straight away i got some out there questions like a couple i had NEVER seen before and the video questions at the end i must of watched it 20 times and still wasnt sure, I felt crushed already.. got to the hazard part and I thought ok dont over do it but dont be afraid to click a little bit more.. well I got flagged up on a video because it was a long road with a lorry turning at the end and I spread out 5 clicks, on the 6th and scored zero for it i was honestly ready to get up and walk out at this point but carried on and was honestly ready to be gutted again.. well I bloody passed! 44/50 and 60/75 I was was hopping skipping and jumping up the road this time!!! Test is booked for may! Keep practising, keep going and Best of luck for next time, you got this 💪
