I am going to attend an interview regarding for my PhD admission in Biomedical Informatics program at the School of Biomedical Informatics, UTH. During the interview, i will have to complete a writing assessment within 1 hour in an online prompt. They told me that the writing assessment is based on a health-related topic and does not require prior knowledge or research. Could anyone kindly explain to me how should i prepare for this writing assessment? Is there any sample question available ??
