do i have to use scholar articles for pip (eg like dissertations stuff from google scholar) or am i able to use articles from eg the guardian (1 Viewer)

[quokka]

ive tried searching this up but couldn't find an answer, i did a practice pip in year 11 and we were only allowed to use verified articles that were like in pdfs and stuff and not able to use newspaper articles like from time or the guardian so just wondering if same applies in year 12? thank u sm
