I would trust your HS Naviance and temper it with major selection, as UCBalumnus mentioned. Somehow, I think that the UCs have the HS’s rigor programmed into their applicant selection computer program. Make sure to add in a few safeties. As for Berkeley, Michigan, or Ivies, you can put them in as a high reach/lottery. 3.8 UW/34 ACT is probably about as low as you can go and still try to apply without some special hook. Check out your Naviance for these colleges as well.
