Not sure what you mean about Good Hooks into social Justice. Involvement in social justice via EC’s, awards etc… are not Hooks but would make for interesting PIQ topics.
UC’s are very unpredictable so I would start your college list by identifying 2 Very Likely/Safety schools. None of the UC’s you have listed would fall into that category unless UC Merced would be an acceptable option.
Spend time on your Personal Insight essays highlighting your passion for social justice and make sure to elaborate on your EC’s, awards and activities. Best of luck and apply widely.
There are 8 PIQ. Applicants are not required to answer PIQ #6. Even if they do, the question is “Think about an academic subject that inspires you. Describe how you have furthered this interest inside and/or outside of the classroom.” Many students do not write about their intended major.
