15 More rules The syllabus is a contract, but it s subject to change. If it is a big change, you will be notified Turn off your cell phones before you enter the lecture/lab room. They can NOT be left on tables during exams You can NOT use computers, tablets, cell phones while I am lecturing in GY 111; but they can be used during my GY 111L lab periods for accessing the class website If you have a problem, contact me via phone ( ) or (dhaywick@southalabama.edu)
