Computing Grades

Going into the final exam, which will count as 2/3 of the final grade, Larry has test scores of 86, 80, 84, and 90. What score does Larry need on the final exam in order to earn a B, which requires an average score of 80? What does he need to earn an A, which requires an average score of 90?

To Earn An B:

(86 + 80 + 84 + 90 + B)/5 = 80

To Earn An A:

(86 + 80 + 84 + 90 + A)/5 = 90

What do you say about my setup?

Yes, that's good and will lead to the right values.

If you want to be pedantic you could write (86 + 80 + 84 + 90 + B)/5 ≥ 80 but it won't alter your answer.

Good to know. I had no clue that an inequality symbol can be applied in this example.

You get a B for 80 or above, so the avaerage may be 80 or a number over 80.

This is interesting. In fact, this is how teachers grade students per semester.

That grading method requires that every year an exam is set with exactly the same degree of difficulty.

If the questions are , for example, harder one year then less students will reach the pass marks for each grade.

In the UK grades are not pre-determined. After the marking is complete the chief examiner and other examiners use their experience from previous years to set an appropriate pass mark for that year.

For GCSE the syllabus specifies what a grade F, C and A student should be able to do which makes it easier to decide, after the exam, if the pass marks are being correctly set.

This also enables people to assess whether standards are rising from year to year.

This makes perfect sense. However, in the United States, the goal is to dumb down its citizens. This is not a conspiracy theory. This is factual data. Students graduate from high school in the United States not knowing what makes up a complete sentence. I worked as a sub teacher for 8 years. The cancer of politics and greed has ruined the American educational system.
