UC-weighted-capped GPA? Calculate by this method: http://admission.universityofcalifornia.edu/freshman/requirements/gpa-requirement/index.html .
For safeties, you may need to see if UCM or various CSUs (not CPSLO, SJSU, or SDSU) may qualify, depending on your GPA and your cost constraints. Note that engineering majors and computer science are often more selective than the colleges generally are.
If you need low cost but won’t get enough need-based financial aid, consider the automatic big merit scholarship schools like those listed in http://talk.qa.collegeconfidential.com/discussion/comment/20798968/#Comment_20798968 .
