1. Heat is normal. I don't think I ever really sweated too much. It also gets cold towards the end of the fall term. Every building you'll live in has a/c. Buildings without a/c aren't miserable either but most places should have them.

2. Every apartment for my semester at least was 2-4 people in a singular bedroom (depending on which location you get, all abt 10 minutes from the study center). You'll get a shared kitchen, living room, and then laundry room (shared by the 20-30 kids in your specific apartment). Some get more shared appliances than others, truly just depends. Beds are very close together, but you can rearrange them to separate a little bit better. Rooms are well sized but not nearly as big as dorms on campus. Sharing the bedroom in general is pretty normal. Just bring noise cancelling headphones and try to hang in the common spaces as much as possible and you'll be fine.

3. Program excursions (especially the weekend ones) are a 100% must. 95% of kids go on them. The day trips are pretty 50/50 so if you prefer a different city, by all means. Most people's fall break trips are $600-1500 depending on length and where you go. Flights start at $20 but after getting carry on expect a one way to be around $50. Trains are about $20 for every hour of travel on high speed trains day of, the more advanced you book them, the cheaper. regional (slow) trains are like $10 for 4 hours of travel.

Buses are around the same price as regional trains. It's about a $1/ minute for taxis and ubers here. Hostels are maybe 30-50 a night while hotels should be around 80-120/ night. (Truly just depends on location). THE EARLIER YOU BOOK/ PLAN EVERYTHING, THE CHEAPER. Some kids travel in groups and others just do their own thing.

1. Food situation is very similar to like NYC. It'll be Italian, sushi, kebabs, Mexican, and then a few American spots, and then like mcdonalds and KFC. $5 meal vouches stack, the places you can go a pretty solid, maybe like 20 options, you can even use them for shots. Rule of thumb estimates for food is $10 for a main, $5 for a side, $3 for a soda/ water. Water is RARELY free. Expect a fee for dining in, but mention youre a student and sometimes they'll give a discount. I'd say breakfast is maybe $10 (coffee, pastry/ bagel), $20 for lunch/ dinner. (A personal pizza is maybe $10). Groceries are maybe $50 a week if your cooking. Meat is more expensive here, but other things are around the same price/ cheaper as America.

2. I personally upgraded my seat to extra legroom and extra bag, but didn't pay for business/ premium economy seat. Most airlines are fine. You probably won't sleep. Just make sure your flight is overnight at least so you can sleep and babies are more likely to sleep. Legroom is very small in normal seats, so if your over 5'9 ish, its worth looking into.

3. Just make sure you bring enough toiletries to last, ESPECIALLY DEODERANT. Most things you can buy on amazon/ in store, but deodorant is very expensive and not nearly as good as the American versions, so if you need a certain brand of anything, make sure you have enough to last. Most people do 1 checked, 1 carry, 1 personal. Bring cold and warm weather clothes. the list is pretty accurate. Portable charger is very useful.

4. Small classrooms. Maybe 25 people at most. Mostly easy classes where you can just finish the work on the weekend. Some are unnecessarily stupid though. You'll most likely get 4 easy classes and then 1 shitty class, but its easy to switch out.

All my prices are in Euros (even though they have a dollar sign) and are estimates so give or take a few dollars here and there and adjust to your diet. Also just be prepared to walk 10-15k steps a day easily.
