Is it fair to punish absent students with a one-question exam?

I encountered a recent post (I do not disclose it as it contains the professor's last name):

The academic record of this course is so low that the professor used suspicious tests to punish those who did not participate in the class. Those who do not have a class obviously fail this exam and those who are in the classroom (probably) will get A. The last sentence about door instructions is "Maybe we will do it again"

Let's assume several factors for the course and question test. It is because I do not know how these are actually implemented.

The course has an attendance policy (for example, I missed it three days before the beginning of the grade).

The impact of this one exam is the same as homework (if you get 0, the total score may drop by 1%).

According to the language of the original article, this does not expect the students to happen; this means that the policy is not outlined in the syllabus.

If there is no attendance policy on the course, the professor is only angry and the students are not present in the class. What should I do? What if I do not score the whole homework, but the value of the exam only has 1 to 2 points?

Is it fair to use this strategy to add additional penalties to students who do not participate in the lecture (moral if you want)?

Clarification: Students who are absent (except interested, unrelated cases) should lose points of work that they missed. However, this strategy is used to punish students for their absence from students; this is the reason why I make different assumptions about attendance policy.

You can not redo the exams and homework. It is unfair for students to be correct first. If a student gets C in the exam and the second student fails the exam but is allowed to take the exam again and take the C exam, it can be said that the two students are in the same grade It is unfair. You have the opportunity to take each exam and participate in each assignment. (It goes without saying, if you can start working again later, the mistaken thinking that you do not have to work hard first will become stronger.

• Practice the AP exam. I used the 2004 exam question and experienced the AP exam on Saturday 2 days before the actual exam. Most of my students have participated in at least one course. Because traffic is difficult, not everyone will arrive at the same time, so we will carry out unit tests in a year instead of conducting regular tests. Students evaluate the following three evaluation methods for the results of the semester. The final exam of the semester is exempt (1 semester) or counts towards the other 20%. When the exam is exempted, 80% recalculate the final score

There is one final exam for this course. You must complete the course section before taking the exam. The final exam contains 10 questions randomly chosen from a number of questions. A score of 70% or more is required to pass the exam. Students who do not pass the exam can pass the exam as many times as necessary to pass the exam. To ensure reliability and strengthen your company's training program, you need to use a training provider. Therefore, in addition to the training provided by outsiders, students also need to take specific site training provided by their company. In this training, it is necessary to take up company-specific danger prevention measures such as use of site-specific equipment, safety and health policy, emergency procedure and so on. In principle, company-specific training requires detailed records.
