Hey everyone, new M1 at CCLCM here. Just wanted to say this school is truly amazing and I wish you all the best of luck with applications. I'd also be happy to answer any questions that I can. Looks like a few people have asked about the research essay.
I would recommend writing an essay that any scientifically literate reader can understand, but don't assume the reader is an expert in the field. Focus on the overarching question the project aimed to answer, the rationale for the experimental approach/design used, the conclusions you drew from the results, and what future directions you considered. I would advise against providing the gory details of an esoteric technique you used. In response to
@Lazy Surgeon's question, our essay prompt last year didn't restrict which research experience we could write about. If the prompt doesn't restrict you, you can probably write about any meaningful research you did (past or present).
