Racemic Mixture

I got into Maryland on Monday, about a week after I submitted the application (holy turnaround). It's not one of my top schools, but it's exciting to have gotten in somewhere. I've also been given an interview at UC-San Diego, the dates being sometime in February. Does anyone know what to expect from these interviews/have any advice and guidance? I figure I should study up on the professors that I'm interested in working with (reading papers, knowing their research) and should be able to concisely describe my research experience, but is there anything I should know beyond that? Also, dress code...I'm guessing a suit?

Hi all, I'm about to be a senior at the University of Wisconsin-Madison, majoring in Chemistry. As a science major, I had no opportunity to study abroad, but I still have a strong interest in living outside of the US. I've been looking into PhD programs in organic chemistry or chemical biology, and have found several at international schools (I'm mostly looking at the UK, but I'm not too picky). I currently have a 3.71 overall GPA, with a 3.86 math/science GPA and have 5 semesters of research (including 2 summers) total, in two different labs, so I believe I have a somewhat competitive application. What I've been wondering is: 1. Does the graduate school process work the same internationally as it does in the US? By that I mean, is it possible to fund tuition and other costs through grants and stipends? 2. Is one able to directly apply for PhD programs after completing your bachelor's degree or do schools require a masters before one can apply for a PhD program? 3. Are many international programs on the same caliber as US PhD programs, or would I be hurting myself applying for a PhD abroad if I don't get into a top tier program? Thank you for any and all help (this process is rather daunting).
