On the subject of grade classifications and passing, I thought I should share my experience on what I have noticed about the type of learners at university
Having just completed uni I believe there are three types of learners: "the progressive learners", "the exam time learners" and the "crammers"!
The "progressive learners" are those that learn the content of the course as it is taught, this way they spend about an hour or two each day organising their notes and going over all the lecture slides, notes and tutorials that they learnt that day. So that when the exam time comes all they have to do is quickly skim over their notes and concentrate the rest of their time on practising past papers rather than revising the course content.
The "exam time learners" are those that work just enough throughout the year to make sure they understand the material and can do the courseworks well. And about 1 month before the exams, they start to revise intensely but focusing mostly on the exam content rather than practising past papers and questions.
And finally there are the "crammers", who spend most of the year copying off their friends work, and overall doing very little work. When exam time comes they either photocopy somebody elses notes or just revise from their own notes filled with doodles and with "very few" annotations. They then try and do targeted revising by revising those topics they believe are most likely to come up.
And from what I have noticed, the "progressive learners" are the ones who mostly get the 1sts and 2:1s. The "exam time learners" get the 2:1s and 2:2s. While the "crammers" struggle behind and are mostly on 2:2s and 3rds.
Although it is possible to classify students into other intermediate categories, I believe that these 3 categories are the most distinct categories of students you will find at university.
PLEASE DO NOT TAKE THIS AS SOME SORT OF A GUIDE!
As It is very possible for a crammer to get a 1st and a progressive learner to get a 3rd as there are other factors such as abilty to understand and learn the material quickly that also come into effect.
