For me the first week is always the hardest because I am used ti waking up at 1:00 Pm by the time summer is here, it is very hard for me to get used to waking up at 5:50-6:15 but I manage. Another thing for myself is finding classes, I notice most people find there classes relatively easy but I myself have to go and search the day before just to be able to make it to my classes. After the initial start of school it is quite easy to get around, get settled and reunite with friends you have not seen for quite awhile. Lunch is also something I missed, not for the food obviously but for the free social interaction that it brings.
