Well not to toot my own horn but I passed my G1, G2, G, M1 and M2 tests all on the first try. 
:A
That being said though, don’t feel bad you did’nt as your not the first and you won’t be the last. Just give it another go and maybe try a different location of you don’t feel lucky there.
I’m sure you’ll pass next time :R .
Good luck.
Cheers
