Hey guys, congrats on your acceptance! I'm a graduating MPH in Health Services, specialized in Management, and I'd be happy to answer any questions. Since several of you are HS, this should help...
First of all, correspondence: You won't get much. Prepare to be living in LA and ready to be on campus for orientations and whatnot at least one week before the first day of class. In HS, you will get an email mid-summer telling you exactly which classes to enroll in for Fall quarter. In HS, one of your four may vary based on whether you choose Policy or Management to specialize in. Several of the required courses are changing this year, so I'm not sure exactly what your list will be, but likely Intro to Health Services 200A, Biostats 100A, Intro to Policy or Organizations and Management, Microecon. At the departmental orientation, they'll show you how to pick classes for the rest of the next 2 years. Only a handful of classes fill up completely, and they are great about getting you in if you need it, so do not worry about enrollment. DO worry about paying your tuition and completing your quarterly data sheets on time! They WILL put a hold on your record/drop your classes if you fail to be prompt. Proactively print your syllabuses (syllabi, if you prefer haha) and look prepared to make the best first impression - it counts! Make friends with Roxy Naranjo, the Student Affairs Officer - she can be super helpful.
Prepare yourselves early on for the fact that very few of you will EVER get ALL your reading done. You'll learn to prioritize certain books/certain classes/certain readings, because you'll ALWAYS have too much. Printing lecture slides ahead of time (I probably don't need to tell you this) is a huge help in many classes, 100% of my classmates do this now. Prepare yourselves to drop $300-500 per quarter on books - Health Sciences bookstore does price-matching with websites like Amazon.com if you bring in a print-out of the webpage. Sharing certain books or checking if they're in the library are great alternatives.
Those of you in HS, you'll get a 2nd year student assigned as a mentor, which you'll receive emails about in August or September. They probably have great resources (used books, old exams, old papers, old posters, old class readers filled with notes) and should be happy to share with you, as I did with my mentee. This year's 1st year class is a great bunch that I've gotten to know, be sure to get to know them and use them for advice!
Internships are a minimum 10 week requirement, 40 hrs/week. You'll get a fair amount of help from the department hearing about opportunities and interviews, but the best thing you can do is ask the 2nd years early on about their experiences. If any interest you, ask them to set you up with informational interviews/coffee/lunch with them and their boss. Saves you a lot of trouble come crunch time! Other breaks/vacations are yours to do what you wish (and are long since finals are often earlier than finals week, i.e. 1.5 weeks for spring break, 3 weeks for winter).
Finally, be warned, I personally was shocked at the amount of work I had during my first year. I was a molecular bio major at UCLA, and I'd say I spent more than twice as much time studying during my MPH as I did then. You'll have more midterms and papers than you think you can handle. You won't sleep much, unless you have ZERO social life. Tools to take advantage of: professor office hours (most of them are MUCH more helpful than they appear to be at first glance), TA office hours (some are more helpful than others), Graduate Reading Room (8th floor of the Biomed Library, has computers/wifi and plugs/macbooks you can borrow, study rooms, food/drinks allowed, armchairs for when you get sleepy and need a nap). Comfort yourselves with the thought that 2nd year WILL be easier, and after that you'll make a great salary
Oh, and pick up a season ticket package for the home football and basketball games over the summer, when they email the offer to you! We had a blast tailgating with everyone this past year, and students who bonded with the 2nd years earlier definitely got more help finding internships, etc...
Congrats again, especially if you actually finished this entire rambling message!
