Postgraduate studies?

I not really think in my "university future" so i not have and specific idea of what topic and wanna studie more in a postgraduate, but is very probably that i take the "Magister or archeology" who teaches in University of Chile. This desicion is because i think that in 4 years (but if we speak with the true only 2, the years of the mention) is little time for learning the important, interesanting and necesary concepts of the archeology, this is because for my bad lucky the first two years of my programm are more focus in the social mention so the futures archeologists and anthropologies fisics are not so considerates.

So i think end my licenciature in anthropology with mention in archeology (4 years) and validated for start the magister for study 2 years more, i remember that Salazar (the director of the programm) telled us that idea, so probably i will had lessons in the university, and will do the practice (i dont know when, but probably in this years). About the topics, i have and ideas in mind not very specific but come on?! i am in second year and i not begin the mention yet..so what do you want of me? i think is valid not had the clear ideas.

 If you want a spoiler...mmm settlement american in Chile, cosmovision and comparations of this, of  selk´nams, yagans, aonikenks, kaweskars and mánekenks culture, management and dissemination of one precolombian culture in this days (heritage).
