# SCI 340 Homework assignments, Fall 2018

## About the dates

Section 1 has lab on Thursday, so homework is assigned and due on Friday.  Section 2 has lab on Friday, so homework is assigned and due on Thursday.  In the pairs of dates given below, the first date is the Thursday date for Section 2, and the second date is the Friday date for Section 1.

## Ragged edge policy

If you write your work in pages from a spiral-bound notebook, trim all ragged edges before submitting your work.  Ragged edges make papers difficult to collate, and will not be accepted.  If you submit a homework with ragged edges, I will return it without comment and it will receive no credit.
