[Online TESOL] I have a question.

Hi. My name is hyun su jin. I've just started to take Business Translation(Advanced- ITT Levle 1,2). At first, I finished first homework just now, and then i uploaded English to Korean translation module but there was an error to save home work..so i didn't finish to upload Korean-English translation module. So, if you don't mind , could you tell me how to upload homework i didn't upload. As well as I did not know about how to use home work submitting system and get any note about online system from GC employee. Thus, I don't want to get a penalty about my homework score. Thank you.
