Stress of Exams

This week I am having my exams. This is very difficult for me because I have some works that I need to make out also for this week, this works have been created in teams but this is not the problem, the problem is that now every afternoon some of the integrants of my team and me are going to the hotel to make hours of service, and this putting me up in a trouble because I don´t have the time to go with they and I need hang on to make the part that correspond for me when I could have free day in a hotel , so I need to draw up an itinerary to me to organize my time.
Yesterday was the day more difficult for me it because today I have tree exams and I am not saying that is difficult for the signatures, I am saying this because for example: tourism exam, I needed learn six states of the Mexican Republic and all of this with their rivers mountains, touristic places, monuments, the weather the typical dishes, archeological zones beaches, etc and that is picking me up time to sleep and study about other signatures like macro economy that I thing that this is a little complicated for me it because I cold study my notes but I don´t know if the teacher will took on this information or if she will put other problems or situations.
The last signature in which I am going to present the exam is “Metodologías de la Investigación” that for me is the more easy because the concepts are very clear but is a lot of information so I think all of this produce stress for me but if I want to grow up like a student and like a person I need to be more concentrated and work hard.
