READ THE FOLLOWING CAREFULLY On exams, you will be required to also upload your work – mainly for partial credit on questions you did not type in work.  This question is here to practice this. You can alert the proctoring service (and instructor) that you are DONE ANSWERING QUESTIONS and ready to: Get your phone. SCAN and UPLOAD your work. SUBMIT the exam. Do NOT edit your work. STAY ON CAMERA while completing your scanning and uploading. Scan your work into a SINGLE pdf document.  Be sure to “keep scanning” so you create a SINGLE pdf. Email this scan/pdf to yourself.  Save the scan/pdf.  MAKE SURE you know where you saved it – and rename it.  Ex:  Quick Quiz Your Name Upload this Scan into this question. Submit the Quiz DO NOT try to upload pictures, jpegs or multiple files.  It must be ONE SINGLE PDF file.
