The purpose of the extra credit assignments is to keep you challenged if you find the regular assignments too easy, or if you want to learn the material at a deeper level than normally covered in class. Therefore, I discourage you from doing extra credit assignments if you have difficulty completing the regular homework. In the latter case, you need to see the instructor for help; otherwise, you will most likely receive low grades for quizzes and tests.

In order to have your extra credit assignment graded,  (i)  you must also turn in the non-MyMathLab part of your regular homework for the same section, and  (ii)  this entire regular homework (i.e., its MyMathLab and non-MyMathLab parts combined) must be more than 70% correct. I will not grade the non-MyMathLab part of the submitted regular homework, but only mark mistakes that you have made (if any).  The hand-written part that you will hand in must be written neatly and stapled. I will not accept a sloppily prepared extra credit work.

As with the regular homework, you are encouraged to seek help of the instructor with this additional homework. However, since this brings you extra credit, I will only give you a hint, but will not guide you through the entire solution, as I normally would do with a regular homework problem.

When doing an extra credit assignment, you may also seek help of tutors or work together with a classmate (but see a Clarification after this paragraph!). Keep in mind, however, that this will be beneficial to you only if you understand the solution and, most importantly, are able to repeat it on your own. I will check, at my discretion, whether you can do so, by asking you to repeat the solution. If you are unable to clearly explain to me the solution of the extra credit problem you had handed in, this will be considered academic cheating. As such, it will be reported to the UVM Center for Student Conduct. In addition, the first instance of it will result in an appropriate (at my discretion) reduction of your final grade (usually by around 5%).  For the second instance, I will recommend to the Center for Student Conduct to give the student an XF for the course. No exceptions will be made from this policy. 

Clarification on how I will handle collaborative work
If you work with your classmate(s) as a group, you should just submit one solution and put all your names on it. (Each group member must still submit their regular homework, as described above.) Then I will divide the extra credit points by the number of people in the group. This will still add bonus points to your final grade, of course; just fewer of them than if you had done the work all by yourself. If you have collaborated only on a subset of extra-credit problems, the above "division rule" will apply only to those problems which you will indicate on the front page. (Example: John and Mary did one extra-credit problem together and, in addition, John did one problem by himself and Mary did two by herself. They submit their separate works but indicate which problem they have collaborated on. Suppose each problem is worth 1 point. Then John gets 0.5+1=1.5, and Mary 0.5+2=2.5, bonus points.)

If a group submits essentially the same solutions that have merely cosmetic differences (at my discretion) and fails to acknowledge collaboration, then for the first time, I will divide the total bonus score by twice the number of people who, in my opinion, have collaborated. This will be regardless of how many problems they have collaborated on.  Please note: Each person in the group is still responsible for being able to clearly explain to me the solution. Failure to do so by even one student in the collaborating group will entail - for everyone in the collaborating group - the consequences described two paragraphs above (and, of course, no extra credit will be given to anyone in the group).
If a submission of merely cosmetically different works occurs for the second time, I will not give extra credit but will, instead, treat this as the 1st instance of academic cheating (see above) for each member of the collaborating group. (I.e., in this case I will not even go to the lengths of checking if every student understood the submitted solutions.) A repeated submission of merely cosmetically different works will be treated as a 2nd instance of academic cheating (see above).

If you are unsure about any of these rules, ask me before submitting your work.
