pass driving test

I stopped every corners and I failed because of unnecessary stop..well the book says you need to stop and check the traffic before you make the turn, I did. Didn’t say anything about only when there is traffic light at the front. So I stopped every corners, my fault. To make a left turn, I stop at the limit line just like what it is in the book. But nope, I must assume and move forward when it’s green light and turn when it is safe…right, I did every thing exactly by the book..how on earth I should know that it is ok to make the assumption, no body tells me that… I felt so stupid, real stupid. I’ve been driving in CA for two months…I turned my head, I checked the traffic before I proceed…what else do I need to do? Eat the book? I hate living all alone in California….Gggggrrrrrrr
