I think the one piece of advice that any student who is wondering if they should go on an MEI trip should know is that MEI is an academic program which requires hard work. Of course, that is not to say you don't get to go out and see the location you are in, but more of a word of caution that you have to be willing to work hard in order to get good grades as you might get in your normal high school.
Since the summer programs are condensed versions of courses you may usually take in four months down into 35 days, you have to acknowledge that you will always have an assignment on the go. My biggest piece of advice is that you shouldn't procrastinate while on the program and always finish with your best work possible.
An average day with MEI is fairly standard across all programs. You wake up and have morning workout at about 7:00 local time until 7:30. This workout is one of the best activities to start your day with. Often, we play ultimate frisbee or other active group activities to wake us up and help beat jet lag. We then head back to where we are staying and get changed and eat breakfast. At around 9:00 AM, we meet again as a class and participate in Morning Note, a journaling exercise which requires 900 words in 30 minutes. This allows us to get ready academically for the day and helps train us to write fast.
After that, we will either already be at our lecture location or we will walk to it. This location is always relevant to the material we are learning that day. After our lecture, we are often assigned an assignment and have around four hours of free time to head out in groups of three to explore the city and work.
In the two course programs, we meet again in the afternoon to have another lecture and head to dinner as a family or small groups. At the end of the day, we have free time to unwind after dinner, get work done with friends in other rooms at the hotel, and go back to our own assigned rooms for room check where teachers give us important information about the next day.
My biggest fear about going abroad was the fact I went alone without knowing anyone else, and being scared that I wouldn't make friends. This was completely changed with MEI from the first day everyone came in to meet everyone with this same fear. The fear quickly evaporated as we really met each other and talked for a bit.
MEI builds a family on each trip where you feel that you truly belong. All the teachers on the trip are easy to talk to and feel more of a mentor than a normal classroom teacher who you might be intimidated to talk to. Once you start to live with everyone and move as a group, you realize that the students you are with are just like you, and you just become so quickly bonded! In the future, I look forward to travelling solo and meeting new people I might have never talked to on a normal day at home.
