Hmm, I only have knowledge of Ontario's program, which seems pretty good.Private student loans have pretty bad interest though At least from what I've looked at (A $3500 loan=paying back $4600 at one place, its ridiculous).
Getting anything better than that is going to be hard though, most rewards I've seen are similar in the amount of money left over to pay. If you decide to transfer to another school in California from there like Berkeley or UCD, then it will be waaay cheaper.
Plus, it doesn't look like your loans (sub & unsub) are even near the maximum, so if you are going into a field that actually has job opportunities, you could get another 4.5k from those loan types and be better off.
