For Midterm • You can use on this midterm: • You can always use yourtextbook & notes • Printout of slides IF has notes on that day's slides • At the same time, you may NOT use: • Computer, calculator, cell phone, or similar • Copies of daily activities and/or solutions • Friends, Romans, countrymen or their ears
