Here is some UCR admission data for comparison from 2018. ME and Biology are very competitive at all the UC’s so the data listed below is not major specific. Expect these competitive majors to require above the averages in stats to have a good chance at an acceptance.
Freshman admit rates for UC GPA of 3.80-4.19 (2017 data since 2018 data is not available as of yet):
UCR: 90.1%
2018 UC capped weighted GPA averages:
UCR: 3.81
2018 Data:
25th - 75th percentiles for SAT:
UCR: 1130-1380
Aim for at least a 1300 SAT and hopefully your UC Capped weighted GPA will be closer to a 4.0 by end of Junior year.
First Generation will be considered if both parents did not attend college. Having parents that do not get along is not considered a hardship in the eyes of college admissions but having some unstabliltiy in your home life and how it affected you might make a good personal insight essay on what you learned from the experience.
Also make sure you identify at least two safety schools that are affordable, have at least an 80% chance of acceptance and you are willing to attend.
Best of luck and keep up the good work.
