How much will car insurance be for a sixteen year old girl who lives in California?

My parents don't have the money (plus they don't want to) to pay for my insurance, so even though i'm turning seventeen this year, I still don't have my license. I'm trying to get a job, though, and was wondering if anyone could give me a ballpark for how much it'll cost a year...I get good grades, I know some places will give you discounts if you have good grades...so yeah. :)
