<p>Pretty much any value that is available on the Personal Profile section of Bearfacts can be turned into a condition for registration or a condition that defines a category for a course whose registration is restricted by categories.</p>
<p>class standing
non-AP class standing
special registration programs (DSP, athlete, etc)
residency (never saw that used, but possible)
college
major
academic status (probation or good standing)
registered or not
units enrolled
degree candidate this semester
UC entry writing taken
AC taken
American history taken
American institutions taken
birthdate (also unlikely to be used, but possible I think)</p>
<p>also some few bits of added data like ‘new’ - first semester, ‘transfer’, and whether an advisor code is needed to register</p>
<p>What the system does NOT seem to be able to do is access your transcript or history of classes and grades. I don’t remember seeing a class pre-req enforced by telebears, it is just listed and possibly enforced by the prof/gsi/department. I have not seen the system enforce a minimum grade in a pre-req class either - someone with a D in a pre-req can still register even though the catalog listing may state that a C- or higher is mandatory.</p>
<p>Even requirements that classes must be taken simultaneously - unless you are in an exception situation where you don’t need one of them - for example Bio 1A and Bio 1AL - are not enforceable by telebears. Instead the department has a coordinator that scans, matches and drops those that don’t meet the conditions. It can’t even look at the specific classes you are already registered for, apparently. It only knows units enrolled, just enough to enforce the phase I units limits of 10.5 units max (or 12.5 for grad students). For the phase II limit, this is why the limit is that if a student has 16 units enrolled (including waitlist), they are blocked from adding additional classes. Instead of implementing a more logical maximum of units, they had to go with what is possible within the limited capabilities of telebears.</p>
