I’m not sure how to interpret your post. Are you looking for some quick “do this kid and you will get in” type of info or are you looking for pointers on where she (and you) can do more research? UC admissions are very competitive and regardless of how much one loves California, many, many in-state students are not admitted. Please calculate her UC GPAs so that you know her chances at each UC. Also look at the CSU system as they do not factor in letters of rec, essays or a list of extracurricular activities.
If you have read through all of the official documentation, you should have found that she will be asked to write four Personal Insight Questions. She has eight prompts to choose from. Prompt two asks for students to describe their creative side. As was stated above, she will be limited in words so flowery starts and rambling or repeating should be avoided. She should write her essays, let others read them, revise, rewrite, etc. until she removes any filler and every word/sentence adds value and insight.
Prompts 4 and 5 ask a student to explain barriers and challenges that they have overcome. If she doesn’t have something significant that she feels she needs to share, I would avoid these two.
The UCs use 13 criteria to evaluate applicants. Half of the criteria are not related to GPA/coursework/rigor. To evaluate criteria 7-12, they read the essays and what a student chose to include in the activities/awards section. Each essay is read at least twice. The readers are given a rubric of what to look for in the essays which is similar to the description under the prompt telling the students what to consider in that PIQ.
For one who wants to go into health sciences, she will likely need a year of bio, chem, physics, calculus, along with ochem. Look for majors where the first two years include those courses. At some schools, it doesn’t matter what your major is - anyone can take those courses. At other schools, priority enrollment goes to students in engineering or bio sci. She should do her research and choose a major accordingly.
If she isn’t passionate about being a doctor but thinks that might be something she is interested in, I would strongly encourage her to volunteer at a local hospital to see if it is what she really wants to do. Other health professions she might look into are nursing, physicians assistant, occupational therapy, physical therapy and optometry. UC Davis has a nice pre-health advising website with pre-req charts for each profession. Choose a profession from the “Health Professions” drop down and then look at the pre-req chart in “resources.” Heath care is a long road and a lot of work. Have a back up plan in case she changes her mind and save money for grad school in case she doesn’t.
In 2023, UC Merced will be starting a BS/MD program with UCSF. Preference will go to those from Central Cal but it may not be limited to those students. She does, however, need to apply for it when she applies this fall so she needs to be certain that medicine is the path she wants to pursue.
