Illegible, hard to read, or otherwise messy submissions, whether handwritten on typed, hardcopy or electronic, are likely to be returned without grading, for zero credit.

All electronic submissions must be made using the upload interface at Electronic submissions in all other forms, such as email or physical media, will be discarded and receive no credit.

Uploaded files must be named following this template:


The substrings hw01 and jar are replaced by others depending on the material being submitted and N is an arbitrary 4-digit number, such as 4231. Multiple submissions, within reason, may be made by selecting different values of N.

If your upload is successful, you will be presented with a confirmation Web page similar to the following sample. You should record the reported MD5 checksum and timestamp.

SUCCESS: Please note the following for your records.
