Please never ever do these three things as a teacher:1. Give a test with 83 questions on it.
2. Give a test with content that:
a. was not discussed in class
b. is random
3. Give a test with wordy questions and answers.
The purpose of a test (or most tests) is to assess or find out if the students know the material. Their grade should reflect the degree they know the information. If a teacher does one of the three things above then they are not fulfilling the purpose of a test and so are not accurately assessing student performance.
Therefore, I plead with teachers to not do the former three things.
