I am a PhD student works in computational theory. I have been doing coursework for nearly three years and right now I am starting to reading research papers. I am making progress very slowly, taking about two to three months to read a paper: even after reading it, I have questions. I have to actually verify every and each sentence of the paper which requires mathematical knowledge, and I have done enough mathematics coursework. I am getting feedback that I am reading too slowly. I have tried to work hard as much as possible, but it is not giving much results. Although there were many times in the past in which I am able to complete the incomplete proofs given in research paper. Struggle basically means completing the incomplete claims or theorems of the research paper.

**Question : Is it okay to struggle with the content of research paper you are reading? and Is it going to improve with time? How to be efficient in this situation?**

What seems to me little troubling here is I am in a surveying phase (reading research papers), then I will move to publication phase. So first I have read the paper then only I can work on them. I don’t How much time other PhD students take to read a research paper. If I am taking 2-3 months for just one paper, is it okay?
