<p>Well, at orientation its pretty much open registration. Your adviser takes you to the library or computer lab and everyone just registers. I suggest you go on ahead of time and try and plan your schedule out so you can register right away so you can get everything you want. After that, your registration time is by total units so pass those APs/IBs/etc so you can get an earlier time.</p>
<p>Advisement on the other hand is when you sit down with your adviser before registration and talk about the classes you have to take and what not.</p>
