Yeah, so the concept of research student I think is quite particular to Japan. When people hear it they often think it means like a post a graduate researcher. But it's not quite the opposite, but what it actually is you become attached to a university as a student, but your not officially enrolled in any kind of course and you gain any sort of qualification for it but you will be Officially affiliated with the university and probably most important with a supervisor. And so the research student period, it can be six months, it can be a year, sometimes I think it can be two years. So kind of I came here as a research student, I honestly didn't have a good grasp of what was expected of me and I was really nervous and what do I have to do? But First of all, my supervisor was very, very good in sort of guiding me in terms of what I needed to do. And it took me about two or three months to really settle in and really feel like, okay, I know where I am. I have a rhythm and a pattern going. But once I had that going, that was really great because it gave me time to study Japanese and really prepare for the entrance exam. So I think it's It really does depend on your supervisor. I have some friends who, as a research student, their supervisor required them to, say, write a paper and publish it within the year. Whereas, in my case my supervisor's main requirement was that I did enough study to get into my course. So, yeah, research student, it's a vague term. It can mean a lot of different things. So my biggest piece of advice is really Spend the time talking to your supervisor and establishing exactly what their expectations are for you. And then, if they give you a little bit of leeway in that, I would really advise that you try and create specific goals for yourself. because otherwise, sometimes people get a bit lost as a research student.
