I am almost 2 years in to my PhD, in the biological sciences. After completing a pilot study in my area, my supervisor has suggested that I try and publish it. He thinks that a lower impact journal would be appropriate for this work, whilst my current and future studies might have a chance in a higher impact journal down the line. I am a little worried however about if my paper gets rejected, how would I explain this in the viva once I submit? This study will form my first chapter. Any advice is greatly appreciated. Thank you
