If you're looking for downloadable files for a course, i.e. Excel exercise files or PDFs, they will be found in an early lesson of the course typically titled "Course Downloads." Please note while many Wall Street Prep courses offer downloadable supplement files, not all courses do.
If you're taking an online exam, some online exam questions reference downloadable Excel files, PDFs and other files. In most cases, if an exam question references a file you need to download, the download link will be provided in that question.
In some cases you may be asked on the exam's start screen to download an Excel Workbook file before starting the exam. If you've started an exam and did not download the file as instructed, no worries. Simply exit the exam and restart it. You will be taken back to the Start screen and can download the file from there. When you start the exam again, you will be taken to the last question you answered.
