			Make sure you have added the ssh-ping security group to your network interface and that you have associated a floating IP address with your instance. The 192.168.X.X IP addresses are private (and cannot be accessed outside of the openstack cluster), the 134.117.X.X floating IP addresses can be accessed from the Carleton network and will allow you to access the wider Internet.

	Each week you will get a progress grade from 0-4, given to you by a TA. If you are being diligent, you should be able to get 4's every week.

	~~You may complete tutorials either by~~		'''Note this has changed for Tutorials 3 and 4.'''
	* attending your assigned tutorial and working there, or
	* doing the work on your own and demonstrating to your assigned TA that you'~~ve completed the work~~
	~~You must finish the tutorials before the assignment based on them is due. (For example,~~ Tutorials 1 and ~~2 must be completed before Assignment 1 is submitted.) Exceptions will be made only if there are extenuating circumstances~~.

	You can find your TA by looking at the feedback portion of the "TA" grade item in cuLearn.		You may complete tutorials in lab or on your own. Submit your answers on culearn, they are due before the next week but are accepted with no grade penalty up until the related assignment is due. (For example, Tutorials 1 and 2 must be completed before Assignment 1 is submitted.)

			Your answers will be graded based on participation, not understanding. Basically, if you make a reasonable attempt at the whole tutorial you'll get 4/4. Partial attempts will potentially be given partial credit; however, you may improve your tutorial mark as long as it is still being accepted. Exceptions will be made only if there are extenuating circumstances.

			While you may collaborate with others and use outside resources, you should indicate the names of who you worked with and cite the sources you used.

			The words you submit should be your own. Please don't copy-paste answers from others, because if you do, you are subject to being reported to the Dean for plagiarism.

			Note that your assigned TA will be marking your work. You can find your TA by looking at the feedback portion of the "TA" grade item in cuLearn.
