UC has recalculated GPAs for a recent previous high school class to establish the ELC benchmark GPA for your high school. Your recalculated GPA is then compared against the benchmark GPA.
The UC web sites describing how ELC is determined do not specify which GPA is used, but most UC references to high school GPA refer to weighted-capped unless otherwise specified. You may want to ask your counselor which GPA is used and what the benchmark for your school is.
