Exam 1 Material: (February)

Take Home Exam 1 (Due Date TBD): StoneAge Data, Ska Data

You may work on this exam individually or in teams of up to three students, as long as each student on the team is dedicating full effort to it.  I encourage you to work together on this one but no freeloaders.

 

Individual Exam 1:  

·         This exam is to be completed individually. 

·         I will send it to you via email (when TBD). 

·         Normally, this would be a timed, in class exam with no notes but there is no way to pull this off this term with everything that is going on and since I don’t care for those lockdown browsers.  So, you can consult your notes, previous assignments and spreadsheets, etc. and there will be no time limit.

·         There are multiple versions of this exam.  Any evidence of cheating will be dealt with ruthlessly – don’t do it.
