Homeworks, Midterm and Final:

All homeworks should be submitted to Canvas in the format of pdf before the deadline. They will be returned to the students on Canvas. Late policy for HWs and Lab reports: -10% per day. Midterm and Final will be in class. 

Lab and Lab Reports (starting week 3)
Students will meet for in person labs (2 hours 50 minutes) once per week beginning in Week 3. 
Students will work in-lab in groups of 3 and will keep a group electronic lab notebook; this will be submitted electronically at the end of each lab session.  Students will also submit a short individual “summary" after each lab that involves summarizing their results and drawing conclusions; this will be due online 24 hours after the end of the lab session.
 
If a student misses a lab due to an excused absence and cannot make it up that same week, we have one make-up assignment (not linked on the website). This assignment is a completely remote lab task that can be graded to provide the points missed by the lab absence.  There is no mechanism for making up more than one missed lab during the quarter.

Grade distribution:   HWs 35%, Lab 25%, Midterm 20% and Final 20%
