She installed a clean PDF reader, opened her own jumbled folder of notes, and started transferring what she trusted into a new document. She skimmed the suspicious PDF for useful headings, not answers; she kept the structure where it helped, discarded dubious content, and wrote her own concise summaries under each heading. She used the installer’s index as a map, not as a script. For parts she doubted — statistical methods and pedagogy theories — she cross-checked with authoritative sources: university syllabi, archived question papers, and a few well-known reference books. Where the PDF glossed over research ethics, she expanded it into a two-page checklist she could memorize.
