Chances for Americans from a regular school

<p>So I'm really considering going to the UK for grad school to get my masters in history. I have a 3.85 and my sat/ap scores were high (although I'm not sure if those are considered) but I go to a state university. Its a great school but nothing ivy league status. What schools should I consider applying to? Is it even worth it to try some of the more prestigious like st. Andrews?</p>
