There are different kinds of reports:
Write early and often - make your Overleaf at the start of the project, make notes there about the papers you read as soon as you read them. Avoid "I will write the related work at the end of the projectâ.
Use these slides for some guidelines for writing (these were made for a 1st semester BDS course, but the tips do apply more generally). Please do go through these - often Veronika's first comment on reviewing a draft is "go back to the writing slides".
Other tips for writing, and doing research projects in general - these were presented by Luca Aiello for all MSc students
