In http://admission.universityofcalifornia.edu/counselors/files/comprehensive_review_facts.pdf , #6 through #14 could be subjectively determined (though not necessarily). However, “holistic” in this case means that admission readers read the application and give it a single score as whole, rather than assigning points to each characteristic and then combining them in a formula (e.g. like CPSLO MCA or CSU EI). Note that “holistic” does not necessarily mean more unpredictable.
