<p>Hey there,</p>
<p>Does anyone know how hard it is to change your major from undeclared to Biological Sciences? Do you think it's possible to change it now, or just after one year? I will be attending UCSD in the fall as undeclared in Revelle College, and I'm wondering whether I should be worried about this. If it makes any difference, I plan on majoring in the Ecology, Behavior and Evolution major.</p>
