During the week I would go to class for about 3-5 hours a day, Monday-Thursday. I thought I did learn a lot in most of my classes, but I do think I could have been challenged more. That being said, I did love the amount free time I did have so I could actually go out and practice the language with the locals. I felt like I learned a lot of content within the classroom and more language outside of it. I truly enjoyed myself in Granada. I made many American and Spanish friends.

I would highly recommend finding an intercambio (student language exchange) or two who are about your age. They most likely will show you the ins and outs of the city you live in, and introduce you to their friends who are also native speakers.
The food in my opinion was great. I just wished my host-mom would have incorporated more fruits and vegetables to our meals.
Another tip would be to join a gym while abroad. Naturally you are going to want to try all the different food and drink options because you only live once, but if you stay physically fit, you won't put on the extra pounds when trying all these fun, new food options.

The school was nice and small. The actual university has over 80,000 students, but the class sizes were never more than 30 students. I just wish I could have had classes with native speakers instead of mostly American students. My professors were pretty awesome, I didn't really have a problem with any of them. They also gave us tips on what the locals do in the city.
I always felt safe in Granada.

The social scene was a big change for me. People eat dinner at like 9 or 10 at night, then get ready to go out, and stay out until 6 in the morning easily. I absolutely loved it. I am not a morning person, and this lifestyle really suited me.
