| Here are some instructions and suggestions regarding homework submission: 1. The odd number Exercises (Ex. 3, 5, 7, etc.) shoud be submitted to Kenneth.And the even number Exercises (Ex. 4, 6, 8, etc.) should be sent to Johnson. For Ex. 3,we will help you forward your homework to Kenneth. But after that, we will NOT grade the homework that is submitted wrongly. 2. It is better to name your homework file and entitle your email as "PHYS4420 Exercise3 Name". 3. The softcopy of your homework should be clear enough. Please check before sending. |
