Mollykins,
In my experience the further up the Educational Qualification system you climb, the less you are instructed. You are more and more expected to use your own initiative! For certain in the Science/Maths field, you will be more and more expected to deduce results and demonstrate your ability to arrive at a logical answer, (perhaps even at times the end result may be wrong), rather than repeat text-book paragraphs, well that was the case in the UK when I did my Masters and PhD, which was quite a few years (30+) ago, However I did part of my Masters in the USA, where that was not the case, there it was more learning by rote! Hopefully you should emerge from the Educational Sysyem with an ability to demonstrate you have an ability to think and reason through a problem/project.
In my humble opinion, degrees have been dumbed down, in order to politically demonstrate that the UK have a greater percentage of students gaining degrees by going to University. You only have to ask what happened to Technical Colleges, Teacher Training Colleges to see that. By converting them into Universities had the effect of dumbing down degrees. This had the knock on effect of making funding to Universities for all, untenable.
You have to decide on what you want to do as a career, then decide how you use the system, both through work experience and the educational system, to achieve your objective.
