Tilly........
Regardless of the outcome of tomorrow, Hold your head high & proud, you,ve built a car

The test is there to ensure that you & others will be safe once you,re on the road, & when someone asks "where did you buy your car from"? You can then reply with " I built it from scratch" a fantastic achievement indeed
I,d like to wish you good luck with the test, i know its easy to say this but enjoy the experience, all the best mate.
cheers
