Hello Readers :)
About the postgraduate studies, I have already an idea of what I would like to do. First I would like to do a Master in chemistry, and after that do a PhD in chemistry too.
The last month the teacher in charge of organizing and seeing the applications to do the master gave a talk to everyone who want to have this information, I went to it and I discovered that I can do the master at the same time that I finish my career. Basically I just have to do one thesis to graduate and to get the master. I am very motivated and I have cosiderer applying for the master when possible. An important thing is that you need some requirements to postulate to the master, you need a minumun grade average of 5.0, bachelor's degree, have not debts, and a bunch of papers like certificate of degree, certificate of university studies with qualifications, curriculum vitae, and some pictures of myself.
If I get into the master I would like to do my thesis about enviromental chemistry, I think that is a very interesting topic and most of all very useful on this days.

After that I would like to aplly to a PhD, I would like to do it in other country (preferable in Europe or United States), because it would help me to use my english and I could get to know other places with more developed technologies that in Latinoamerica. But I still need time to organize myself better, mentally prepare for those changes, and to decide if I am going to take some time before I finish the master.
For now I am going to focus on looking at issues related to money, because apparently the scholarships that the state gives are very limited (about 13% of applicants obtain them). And as for motivation, I have plenty. :)
