Create a workflow for students to automate school tasks using Shortcuts on iOS. Include: 1) An alarm that requires physical movement to turn off completely; 2) A calculator to determine current academic week based on semester start date; 3) An automated system to collect homework attachments from emails, track submissions, and identify missing assignments. For each component: explain the logic, provide step-by-step instructions, and include error handling mechanisms. Also discuss potential limitations and workarounds for iOS version differences.
