This is my last semester as an undergraduate and I am taking a graduate course in a physics field I was interested in (won't mention the name since I do not want to offend anyone who is researching in this field). The class ends with a report in which we have to summarize research in a particular subfield. Looking over and reading papers to write this report, I realize I do not like this subfield at all. The papers are confusing and technical; I have a basic understanding of each of them but not a thorough understanding of all of them. So far I have read 7 papers and I am comfortable talking about and explaining the methodologies and results of 3 of them; for two of them I am comfortable talking about the methodologies but not the results; and for the last two I have a vague idea of the procedure. I also do not have the stamina to read more papers. I find the topic boring, complicated, and difficult.
What should I do? Should I abandon the idea of going to graduate school? I do not really want to go to industry that much and I really do like physics. Or should I try exploring a new field in physics? Or will an advisor in this field be helpful, since I am reading the papers on my own to write this report and no one is guiding me?
Any advice will be appreciated.
PS: I am not enrolled into a graduate program yet.
Update: If I go to another field in physics, what should I do to see if I like researching in that field? Should I read papers, introductory textbooks? What papers would be the best for a beginner like me? How can I find introductory papers on, let's say, arxiv (is there some kind of section called "Basic"). I am not enrolled in a graduate program yet, and thus I do not have an advisor, so I like to know what I should do in the meantime. Also, my parents and relatives are not researchers so I am kind of alone in this right now.
