We recommend that you purchase a thumb/flash/usb drive and store your homework on the flash drive.
Do not save/store items on the lab computers. The lab computers have a set configuration which is locked. Once you log off, any information that you may have saved to the computer will be removed. **Always save your homework to your thumb/flash/usb drive.
Please keep a backup of your work because there is always possibility of data loss. You are ultimately responsible for your electronic documentation just as you are responsible for non-electronic documentation.
