Exam requires self-imposing a time limit: what should I do when others are likely to use more time? I am enrolled in an upper level STEM class.
My teacher has recently announced that we have a &quot;downloadable&quot; midterm. The midterm is not officially timed, and we have a week to submit it, and there is no way the teacher can track how much time we have used. Now, in class and in a clarification request, it was stated that we have a total time to &quot;work on it&quot; for 3 hours tops, even though we can &quot;look at it&quot; for longer.
I have no clue how to deal with this. A good number of my (normally obsessive/honor code) friends have already told me that they will use more time than what is officially allowed to work on the exam. Based on the sample I've conducted with the people in my year in the class, I would say its highly likely at least 50% are planning on using more time than allowed.
Ngl [not going to lie], I've had to deal with &quot;other people using more than they should be&quot; for at least two of my classes (all of which are online) this semester and I don't want to deal with it in a third. I'm frustrated.
Is there anything I can do?

Solutions I consider:

Students protesting — I don't think anyone is being obsessive about
this mess apart from me.

Confronting the teacher myself — for one thing, I'm not sure if I
am liked by this person (LOL) but I'm guessing if I say &quot;yo there
are students planning on cheating&quot;, this person will simply send out
an email stating &quot;don't cheat&quot; to the class.



Notes:

The people in the class of my year already know about all this mess of a situation because I discussed the strange rules in our group chat, so I suspect if the professor sends out an email I can be immediately linked as &quot;the person who prompted the kerfuffle&quot;.  also I'll be known as the rat. I don't care too much about my reputation, but nonetheless this isn't super pleasant. I probably shouldn't have done this, I see now that it is kind of coming back to bite.

Certain details have been changed or obfuscated to avoid identification.

I'm estimating likelihood of cheating based on an informal &quot;poll&quot; I gave in a high-effort group chat; to get a picture of this group, its a bunch of overachieving underclassmen who I don't think would ever cheat in normal circumstances. I have evidence of intention to cheat, I am not willing to submit it to my teacher.

What I would hope from my teacher would be that the &quot;time cap&quot; of 3 hours would be removed; this obviously is going to get violated anyway.

I specifically asked the professor whether we &quot;must not&quot; spend more than 3 hours on the test; he confirmed that 3 hours is a hard limit.

The class is graded on a curve.



What I'm probably gonna do:
I don't think I should contact the professor directly, mostly because I think this person doesn't like me that much. I think my solution is just going to be to email this person anonymously and express that I have concretely seen evidence of people intending to cheat, though I'm not ratting out any fellow students, and I'll request that the time limit is lifted.
You’re in an unenviable position and I don’t have clear suggestions how to proceed. But at the very least, it’s worth calling attention to the fact that

your instructor is neglecting their duty to maintain an acceptable level of academic integrity, and

this may rise to the level of being more than just a “feeling” but an actual violation of university policy.


For example, at my university, our guidelines about faculty responsibilities in connection with academic honesty state (emphasis mine):

Academic honesty is an integral part of the University's educational mission. According to the UC Davis Code of Academic Conduct, all members of the academic community are responsible for the academic integrity of the UC Davis campus.
[...]
Faculty are encouraged to promote an atmosphere of honesty in the classroom. For example.
[...]

Use exam and assignment formats that discourage academic misconduct.


Now, to be clear, I’m not suggesting that this is grounds for an official complaint or to ask for the instructor to be punished or anything like that. But the point is, if and when you choose to complain either to the instructor or to other campus authorities (department chair, office of academic integrity etc), citing relevant university guidelines or policies can be a good way of strengthening your case and reminding people that academic honesty is a two-way street in which both students and teachers have responsibilities. When the teachers are neglecting their own responsibiltiies by creating such obvious opportunities for a “thought crime” form of cheating that cannot possibly be detected, they can’t very well expect students to fulfill their side of the bargain.
Good luck! Sorry you have to deal with this nonsense.
