Thаt is pretty much it! Nice аnd eаsy. This is the last questiоn fоr this practice test, sо I want to remind you of a few things. 1) Don't forget to turn in your scratch paper containing all your work to the link below this test within 20 minutes of finishing. That should give you time to get it scanned as a pdf. If for whatever reason you can't submit through blackboard, make sure to email me that work instead within the time. No work means no grade, so it is important I get it!2) Be watching for this grade to appear, and when it does PLEASE READ THE FEEDBACK! That is where I will tell you if your camera was placed correctly, if there were any issues with your work submission, etc. You will want to read that before taking exam 1 so that you don't make any of the same mistakes.3) Just as a reminder, the ONLY thing you can have on the exam is blank paper. No notes, homework, books, phones, etc. are allowed on the exams!Other than that, please email me if you have any questions! For this final question, please select "True" if you understand the three above points.
