American colleges give out a GPA, which used to mean something but has now been inflated to the point of meaninglessness. 60% of my college class 10 years ago had a 3.5/4 or higher. The median grade at Harvard is an A. I am told that since COVID, B grades and below now require a written explanation by the professor at several schools.

The only entity that has ever cared about my college GPA has been other colleges when I signed up for grad school. And even in that case it is just a "stat check" in gamer parlance. 3.0 or greater, yes. Lower, no. That kind of thing.

Zero employers have ever asked to see my college GPA after graduating almost 17 years ago.

As prices for college go up, the student is more of a customer than anything, and therefore the pressure to raise grades goes up. Who is going to go to a college where people tend to need an extra year to graduate, when each year is 60k? Or one where only the top 5% of a class gets a top grade?

You are already seeing grade inflation in the UK too: Go look at the percentage of first class degrees over time.

The only place where a modern US university can be used as a filter is in their own admissions, where they can still be pretty stringent. Harvard could fill their class 6 times with people that are basically indistinguishable from their freshman class, so just getting into the right university already shows that you must have had some skill and maturity by the time you were a junior in high school.

This is also why hiring juniors is so difficult nowadays for software: Having successfully finished a CS degree at most universities says nothing about your ability to write any code at all, or analyze any complex situation. And with the advent of leetcode training, it's not as if you can now tell who happens to be good because they remember their algorithms and data structure classes really well. You have no idea of how good the new grad is going to be when they show to the interview, and even those that pass might not be all that great in practice, as they might just have spent 3 months memorizing interview questions like an automaton.

All serious applicants have the maximum grade, in the US system.

Yes but it is not standardized at all. Every college has its own way of doing things. Even every degree or school within a university can be different in how they handle grades. Some places put every student on a curve, so that a particular distribution of grades is always enforced. Some places operate on more of a pass/fail basis - often this is done for the first couple years to avoid measuring students when they’re adjusting to a new lifestyle (meaning partying a lot). Some places tend to give out easy grades. So you cannot compare students across different degrees and colleges.

This is the dumbest idea ever because it forces students to take easy classes instead of interesting ones.
