Remembering my experience of studying

Hello everyone. My name is Elena Sánchez and I'm from Ciudad Real, in Spain.
I received a degree of Chemistry at the University of Castilla La Mancha. I decided to do it because I've have always liked Science, especially Chemistry. I think it helps us to understand the things that happen around us.
I remember when I was studying, the most difficult subjects to me were physics and math. I worked really hard during those few years, especially in the last two terms. I had to write many essays before the end of every term and to study for the exams at the same time, so I couldn't go out for a long time. Finally, I got really high marks.
What I liked most about studying was that I knew many people and I made many good friends.
On the other hand, what I didn´t like was that I didn't have enough free time to enjoy my hobbies because I had to study a lot. Moreover, I didn't have much money.

Thank you everyone for you're input. I am truly an English speaker and I guess I will just have to "wait it out". I also take classes so this is not my only form of language-learning but was hoping to help out others while I work on my conversational skills.
