I did the Motorbike/Car combi test for the C1E and I was required to get at least 90 out of 100.
It should all be the same around Shandong, Gra, so don't worry.
BTW my other friend, Graham, has returned to China now and his Chinese parents in-law just bought him a 90K rmb car even though he doesn't have a Chinese licence.
I'm helping him through the question banks now and he HATES the lack of sense in the majority of the questions. Lol .
