• Submitting editable Word files unnecessarily
• Uploading multiple files when one PDF is required
• Ignoring file size limits
• Using screenshots instead of proper documents

Recommended Workflow (Professional Method)

1. Create or finalize your document.
2. Convert to PDF.
3. Combine supporting documents.

5. Preview before submission.

This workflow maximizes acceptance rates across online systems.
