Lets be honest, that 20 hours independent for 1 hour contact time doesn't happen... How many people do you know that read for 80 hours a week as well as lectures?
My course has something like 21 hours of lectures, 2 general 1 hour tutorials, 1 hour long maths tutorial, 1 lab of 2 hours. Weekly. I'm expected to do a lot of reading - something like 2 hours per hour of contact time. Please don't try to tell me a liberal arts degree is as hard as an engineering or physics degree.
Where did I say anything about one degree being harder than the next? Get down off of your horse, there's no need for you to be up there.
The work I saw Art/Fine Art students do compared to the work I personally did (a traditional degree, but I'd still imagine you'd deem it inferior to your hard sciences, but let's put this straight right now) made me quite angry if truth be told: they can coast through three years and then do some ambigious A4 write-up where a large majority simply don't know the concepts they're playing with actually
are, mean, or are called. They can't even value them, they just pass off the ability to sound like the do, and they still can walk with a degree. Whereas I had to work my backside off, picking up and dropping books on different subjects like they were going out of fashion, and trying to tackle a subject at university level often within days of being introduced to it. It's not easy.
Just because a subject doesn't specialise, doesn't mean it's easy. Far, far from it. Sometimes for that very reason, it makes it far more difficult as you're constantly wading through unfamiliar water. If you're specialised, at the very least you can draw upon your previous education on the subject and simply expand on it. Let's take your example above: most of us here won't be able to tackle that (I suppose half the reason why you've posted it), yet if it's only worth one mark, then you should be able to tackle that easily as you're already advanced in that area. At least your exams have the decency to break down where the marks come from. Let's see you write an essay on a given subject you learnt two days ago and try and get a good grade shall we?
If Nitefly's doing four hours a week in probably what you'd deem a 'liberal arts subject' is easy, then I'll eat my hat. The reason he has so much free-time is so he can read and the reason he has to read so much is because he has
a lot to take in from many different subject areas. The same way a select few of the softer-sciences demand. As Nitefly said; you have to learn to work smart. That requires, whether you've realised it or not, a bit of brain-power.
So, before you get back on that horse of yours, remember that what's easy and what's hard is completely subjective, and if you're going to jump down my neck in future, at least have the decency to actually have a pop at me for something I've actually claimed or said.
