Make a checklist for each application
Start from the institution's own instructions. Record the course, intake, deadline, required files and submission method. Do not assume that a document accepted by one university will meet another's requirements. Include any portfolio, research proposal, interview or additional form in the same checklist.
Keep identity and academic records consistent
Use clear scans with all required pages visible. Check names, dates, grades and qualification titles against the original records. Where a name differs between documents, ask the institution how it wants that difference explained. Keep original files separate from translations and certified copies so that every version can be identified.
Prepare evidence, not a larger pile of files
Submit what is requested in the requested format. An employment letter, portfolio or language result should demonstrate a relevant requirement. Follow instructions for certification, translation and file size. Do not alter a record or omit an unfavourable result that the application asks you to disclose.
Give referees time and context
Ask referees early and explain the course and deadline. Share your current CV and a short account of the work they can fairly discuss. Some institutions require confidential references submitted directly by the referee; do not replace that process with a letter uploaded from your own account.
Do a final submission review
Check the course and intake once more, open every attachment and review the answers as a single story. Save a copy of the submitted application and confirmation. Maintain a separate list of outstanding conditions after an offer arrives. An offer letter can still require additional evidence before enrolment.
