William and Mary and University of Rochester are worth exploring.
The merit award is made when admitted with no extra application. You don’t need to be in the Honors College to get merit money as there are several levels of OOS merit. NMF award is automatic upon acceptance. Check their website under OOS awards. Your S would likely get the Cooper or McKissick, plus gets the Lieber on top if NMF. You do need to apply to the Honors College and that has a fairly early due date (11/1 I think).
He needs a safety safer than UCSD.
The University of Richmond in VA has an excellent business school, including international business paired with foreign language, and has international studies as well. Your child’s 33 ACT would put him at the 75%ile of applicants, and the admissions rate was 31% last year, so fairly selective, and actually a good match for your child’s stats. Study abroad programs at UR are well-supported and approx. 60% of students study abroad. UR has approx. 3200 undergrads, and a gorgeous campus. 90% of students live on campus all 4 years, helping build a true sense of community.
I have one daughter who just graduated from UR and one who is a rising junior, and they have both had fantastic experiences with awesome professors, excellent advising, opportunities to do research starting freshman year (common in all subject areas, not just science), and also paid summer internships. It is very common for students to double major, one of my younger daughter’s friends is double majoring accounting and biochemistry. My older daughter double majored in biochemistry and computer science. It is not unusual for business majors to double major in something else. They do also offer 45 full tuition/full ride scholarships to freshmen each year, along with some smaller scholarships.
Your son’s current list looks to be too full of reaches with extremely low admissions rates. Do not make the all too common mistake of applying to mostly reaches, increasing the odds that your child ends up with very limited choices come May1st. Add some more match and safety schools to the list.
@mamag2855 My son attends a high school in CA which produces around 45 to 50 students who get accepted to UC Berkeley every year (it seems to me that 60 students every year get admitted to UC Berkeley or higher ranked colleges) and produces around 30 NMSF out of around 450 students, so frankly (even though I know this does not guarantee anything), I would be surprised if he doesn’t get into at least one school out of UCSD, UCLA or UC Berkeley. But unless a school outside CA has a clearly stronger brand name, I rather he attend a UC college so he won’t have to pay a high tuition since he’s a CA resident. Also, if he’s lucky to get a Regents Scholarship to defray CA resident tuition/costs, that would be even better. However, as a prudent course of action, we ARE looking to add around 2 more safety schools such as GW/American/University of Richmond/Univ of South Carolina, but he probably won’t attend one of these school unless they offer almost full tuition ride. One really smart student my son knows already decided to attend University of Richmond on a full ride scholarship. Heck, if he doesn’t get into one of these schools, he has an option of studying language abroad for one year for free on some scholarship and apply again. He might do a gap year even if he is accepted into a school he likes simply because why pay $40K per year to study one year abroad when you can do that for free after high school?
I also do not place too much importance on ACT/SAT scores, and I do not believe good schools care whether a student gets 33 or 35, especially when he got 35s on English and Writing/Grammar which are more closely related to his intended major.
And every April on this site, there are students who were surprised. Add a safety.
@usualhopeful, If he doesn’t get into at least UCSD, he has an option of studying abroad for free after high school and apply again, but we are going to add one or two more “safety” schools just to be very safe.
@websensation GW and American aren’t actually safeties. They are sub-elites that are really concerned with yield. They get a lot of cross-applicants from Georgetown just trying to apply for the “DC factor”, so they want to make sure you aren’t treating them as a safety. In order to keep yield up, they deny a lot of people with high stats. At the same time, they award scholarships to a lot of people with high stats if they actually believe they will attend. Just remember that even though they should be safeties by pure numbers, they want you to show them some love.
A 33 ACT score is excellent, and your son sounds like he is an great kid and student, but with the low admit rates at many of the schools on your son’s list, admissions is simply a crap shoot for everyone. A 33 ACT is an average score for Georgetown. Highly selective colleges deny admissions to the vast majority of applicants with excellent qualifications year in and year out. When the process is done, you want your son to have good choices. If your family prefers a CA school for your son, certainly a good deal financially, consider adding a few more state schools which are less selective as safeties.
@mamag2855, The problem is aside from UCLA, UC Berkeley and UCSD, there doesn’t seem to be a UC school with a good IR program. 
There are several private schools in CA with good IR Program though, but they cost more than other private schools. Lol
@TheAtlantic, I see. Didn’t know that. Heck, might as well go to a community school and then transfer. Lol
@LuckyCharms913, One more question for you. I looked at the info you mentioned, but I couldn’t understand how Univ of South Carolina calculates high school GPA because it says average GPA for some scholarship is 4.6, which is impossible at the high school my son attends. The highest GPA every year at the high school my son attends is around 4.38 or 4.4 because they only count AP courses and only SOME Honors courses as 5.0 grade. In other words, most Honors classes are accorded 4.0, not 5.0. I might persuade my son to put down Univ of South Carolina as the designated school on his National Merit Finalist application IF he makes it. At this point, we don’t know if his 221 SI score on PSAT qualifies for CA because we just don’t know what the cutoff SI score will be for CA.
USC recalculates GPA to the uniform SC scale. You can google it.
I think much of the south uses a weighting system where points are added directly onto the cumulative average for every honors or AP class.
If the UC’s or other schools on his list have early notification dates, it’s possible he’d know if he is accepted or rejected from the UC before he has to send the safety applications. My kids each applied to just one school each with rolling notifications. They each knew they were accepted in November, so had no need to send any more applications. They were both fine with the alternative of taking a gap year too.
It sounds like your son has a good back up plan of studying abroad for a year, which may even become the #1 option.
UCs have no early decision applications. Bad, bad UCs. Lol
I was concerned by your statement that you’d want him to “try hard for merit” for the (reach) schools outside California. Harvard doesn’t give merit, and I believe Stanford only gives athletic scholarships outside of financial need. So he can try all he likes, but it’s not happening. Those schools, if he is fortunate enough to get in, are going to be full pay.
Here is a link to the thread about GPA from the South Carolina forum that might be helpful:

Also, choosing your #1 school for NM doesn’t have to be finalized before next spring sometime (maybe May 1?). Hope that someone with more knowledge on this might weigh in.
Yeah, I didn’t really like the campus at GW either, but my D, the one who was actually going to college, loved it. She did not like American’s campus, thought it was too small for her, although the school tried hard to convince her to go there. She had good stats and was rejected by Tufts and Georgetown, accepted to BU and BC. Her husband attended Georgetown’s foreign service school, and seeing what his classes were like, she realized she was very happy where she was.
@mamabear1234 How were the classes at Georgetown?
@donnaleighg Thanks for your concern. Yes, I should have said outside CA schools like American and GW, not Stanford or Harvard.
