Anna: Well this is a tough one. I suggest just distract yourself with things you can do at home while keeping up with your studies so it doesn't seem much like torture. Go watch some movies, TV shows, bake yourself a cake, but don't forget your homework.
Reign: Set an end goal after your summer semester. Try to plan a trip at the end of the term so that it will sort of motivate you to want to get through the upcoming weeks. You can always take day trips on the weekends to somewhere outside the city that's not that far from home. But I also suggest making new friends in your classes so school won't be that boring and uneventful for you.
"Any tips on traveling with friends? Like a whole big group of friends for abroad trips?"
Anna: One thing you guys should NOT do ever in a foreign country is freak out. First, you're going to attract a lot of attention, in other words danger. Nothing spells like an easy prey for pick pockets than confused tourists. Second, don't do the plan where the responsible one has everyone's passports. The safest place to put your passports is the hotel safe. Third, don't wear backpacks because it just makes it easier for pick pockets. If you must, ask one of your friends to watch your back or put a lock on the zipper. Fourth, don't forget to have responsible fun! Fun doesn't need heavy alcohol or drugs, just good company!
Reign: Try to save money as much as you can prior to your trip! Get the best deals for plane tickets and whatnot but make sure your airline is trusted. Travel agencies can also help you book a flight and a hotel for a cheaper price! I always believe that you should try to travel in an even number. That way you can have a buddy system in case someone wants to go somewhere else other than where your group is. Be mindful of your things! Use bags that are slash-proof and complicated to open (i.e. a leather bag with a flap and a zipper). Also, don't bring all of your money everywhere. Try to budget everyday and leave the rest of your money in the safe box of the hotel, but don't forget to bring extra cash just in case. Have fun!!
