Unfortunately, it seems like your father both does not understand college admissions in the USA while, at the same time, is certain that he understands them better than anybody else.
You can show him the fact that the percent of student from liberal arts colleges who do PhDs, or who end up working at top companies, is higher than for most of the universities that he considers to be so great. Talk about the low admission rates, show him the average SAT scores of the students who attend these colleges, as well as the fact that a far higher percent of students from these colleges do their PhD than from either UCLA or Berkeley. You can also show where the graduates of these colleges end up working, and show him that these are great colleges for helping you get a good job.
Why does he think that having a graduate school is a benefit for an undergrad? It just means that there are a lot of graduate students and that you are more likely to be taught by a graduate student than by a professor.
Also, the Claremont Colleges (Pomona, CMC, Pitzer, HMC, and Scripps) do have a graduate school, and a very good one at that.
He should also know that the crime rate around UCLA is FAR higher than around Northwestern.
Show him the Common Data Sets from the schools that he thinks are the best ones for you, where they write the factors which they consider in admissions. It may get him to understand that admissions are not just about GPA and SAT scores.
Also show him the news reports about how the UCs and other top colleges are going to be either test optional or test blind next year, you your SAT doesn’t matter at all.
Also show him some basic statistics - that your chances of being accepted into the universities which he thinks are appropriate are not that high, even though you have top grades and scores.
I’m sorry that you’re dealing with this - having parents who are at once super controlling and clueless is really difficult.
Good luck!
