Jasper #EconomicsCat recommends Cambridge Libguides for help with your study skills: https://libguides.cam.ac.uk/skills
The Study Skills Libguide page has everything you might need from Copyright advice, creating a Conference Poster, Good Academic Practice and Avoiding Plagiarism, Reflective Practice through to more specialist advice such as how to do a Systematic Review, Text & Data Mining and Reference Mangement. There are also Reference Management guides for particular software such as Mendeley and Zotero.
This could be really useful over the Christmas Vacation when you may be working on your own independent projects or essays.
