Senior Standing
Thought I'd post one I see on the board a lot: the dreaded Senior standing determination!
The sweet spot for UC transfer admission is as a Junior transfer. If you have only attended 2-year institutions, then even if you exceed ~90 semester hours you will be considered a Junior transfer on the basis that you haven't completed any upper division coursework. On the other hand, if you _have_ attended a four year university and you exceed this limit then you are in danger of being considered a Senior applicant and denied admission.
In brief, policies on this matter vary from campus to campus and even among campus colleges. Suppose you have earned 100 transferrable semester credits. One university might reject you automatically if you attended even one class at a four year university. Another university might only reject you if you've earned a certain number of those credits at a four year university.
You can find these policies in the "Applying for Admission" section of the "Transfer Q&A" counselor resource. The current address is:
