I find that when people say employers only really care about the class of degree really quite unfair. For example the percentage of 1st degrees from coventry is like 60 percent and then the percentage of 1st degrees from warwick (in a stem subject) is like 20 percent. But i would say on the whole as a measure of intelligence in the stem subjects anyone who gets a 2.2 or above from say warwick would be more intelligent than 95 percent of people who go to somewhere not as prestigous like coventry.
So basically its really unfair, they should look at the institution.
You'll find it even more unfair when, after your first job, nobody gives two shits about your degree.
Because its not done on percentages, so a certain percentage of the students get a first ect the system is competely messed up so getting afirst 2.1 or 2.2 really has no meaning whatsoever unless you compare to people at the same university doing the same course
There's no point in whining about it not being fair. You picked your course, you picked your uni. There is quite literally nothing you can do about it other than get the best degree you're capable of.
In this day and age a degree doesn't even help you that much anyway unless you're lucky. The majority of people I went to uni with ended up either doing another degree, or a job that they could have done without doing a degree (and in some cases without doing A Levels).
Life isn't fair. There will be some things that work in your favour, others that don't. That's a harsh fact I've learned over the past few years.
Things like work experience and contacts are more important than your degree anyway, so focus on getting those.
Who cares, just go do the best you canand stop worrying about what Joe Bloggs from the University of Shitesville is doing.
