UCSD Political Science / International Relations Hard? (undergraduate)

Hello Tritons,

I’ve admitted for the Fall 2016 as a Political Science / International Relations major.
It would be great if you guys can give me an advise for the following:

  1. How hard (academically) is the poli.sci class at UCSD?
  2. I'm planning to go to law school. Does UCSD Poli.sci department will provide me some resources about the LSAT and law school?
  3. I heard that IR (International Relations) major are competitive in UCSD, how good is it do you think?

Thanks!
