Excellent! Thank you so much Phdbug. I truly appreciate it. Your suggestions and examples have been quite helpful.
Nice to know then I do not have to repeat myself with the work experience, CV, and qualifications deal this time!
Best,

I am filling out a postgraduate research application and it states to write our research interests, list publications/reports, if any, whom I would wish to work with (potential supervisor), and to outline a research proposal (max 250 words).

The research proposal, publications, and the potential supervisor, I believe I've got that covered. However, I am a bit confused what to write under the "research interests" part since I am already stating it under the research proposal. Are they looking for something else for us to add under this section?

I graduated from the same university not too long ago (MSc) and do not know if it is pertinent to repeat everything I had written down for that admission (supporting statement: taught course, tell us about any relevant qualifications and reasons for wishing to study this course, attach CV, etc.) or keep it short to why I wish to pursue this area of research, how I feel I match the requirements for that lab, and why I wish to work under that particular professor's supervision?

Many thanks in advance.
