Hi, I'm a Chilean IB student, just graduated from school last December, and want to apply to Oxford's PPE course this year.
Do you know of any preliminary reading that you would recommend me?
Also, how can I practice for the TSA? I've checked out the official web page and the verbal Critical Thinking questions I find pretty easy but I can't figure out a lot of the math Problem Solving ones. Do you know where can I find advice, exercises, or even more practice tests?
