Start with the official document list
IRCC lists identity documents, language results, education evidence and work records among the information that may be needed for Express Entry. The documents that apply depend on your situation. Use the official list as your starting point, then follow the instructions in your own account.
Give every input an evidence trail
Create a private workbook with a row for each fact: the value entered, the supporting document, its issue date and your next action. Separate a missing document from a fact that is confirmed as zero. Keep scans and identity numbers in secure storage rather than in a public score-sharing link.
Review changes before updating a profile
When a passport, test report or employment record changes, revisit the corresponding input and save a dated copy of your calculation. This worksheet is an organization method; it does not replace the application checklist or establish that you qualify.
