If a particular student were to receive a bad grade or low marks for an assignment that they have invested a lot of time and effort into researching and writing, such as their assignment containing a lot of very important and very relevant information, data, facts, statistics, diagrams, photos, etc, has a lot of good references and citations, is well-written in good English with very few or no spelling, grammatical, and punctuation mistakes, is very well-organized in a way that allows the examiner to get a very good understanding of the student's arguments, and is well-formatted, they should ideally be rewarded with a relatively good grade and/ or obtain high marks for such a well-researched, well-written, and well-presented assignment.
The grades and marks given by teachers should be directly proportional to the amount of time and hard work that was invested into the overall development and final production of the assignment itself.
Any assignment that is well-researched, well-written, and well-presented should be given good grades and high marks, and vice versa.
There are some teachers who are very stingy and very miserly in giving out good grades and high marks, as they always prefer to give out bad grades and low marks regularly to every student instead, regardless of how much time and hard work that students have provided in their assignments.
This is very unfair and very unreasonable to any hardworking and well-meaning student who has genuinely put in a lot of their precious time and effort into the preparation and production of their assignments.
Any good examiner will be able to tell that a particular assignment has been done in either a very comprehensive and very thorough way, instead of a very haphazard way.
