I mean the diesel engine department would probably be quite big for a company like Volkswagen. Each engine type has a team of engineers and a manager.

Just a reminder that Reddit was once difficult for people to understand.

To be honest though, I’m a bit disappointed by the other users here. The quality of comments is really poor, both idiotic and adversarial. I’m talking fox news comment section level.

If you haven’t tried it already, I think there’s a lot of benefit to using khan academy and Duolingo for maths.

Maths by its nature is a bit abstract, but I think that the primary issue is that it is sequentially learned for the most part in primary and secondary education. If there is ever a point that a student is struggling with a concept and the teacher/parents don’t identify it in time, the student is then faced with not understanding new concepts afterwards, and may just be left behind.

This is starkly different to other fields a student will be presented, they generally will have multiple topics that are not strictly reliant on parts learned before, and that can be relatively easily co-developed in everyday life.
