I've already missed a lot of opportunities (compared to other students my age). Hopefully I'll be able to do more in school and outside to be able to look more appealing to the admission tutors at Oxford. My mom now seems only concerned about the distance between my parents and me, money, and "where I can go out in service". Unfortunately my parents are more cautious considering my sister, though still a JW technically, doesn't go out in service or meetings after going to college and getting an internship at a major accounting firm. We'll see, but hopefull the forces of the Universe can help me fulfill my dreams to go to Oxford.
On the topic of why PPE, I've looked at many courses and since I'm not exactly sure what I want to be (a politician would be great, but a lot more other careers also look appealing, so I'm confused about what I want to do), PPE covers a whole range of careers under my range of interest, so it looks great for me.
Also, the Watchtower does have its own "university" - Gilead and other theocratic schools. No way in hell am I ever even going to think of going there.
