I have heard that there is actually not that big a demand for engineers any more and engineering is on the decline. I dont know if this is true, can someone help me out because I am thinking of doing engineering at Uni.

#83070 Computers and Electronics...Engineering

Posted by AM4R on 05 June 2006 - 07:06 PM in Course Choices

Hi I need some advice tongue.gif

Well basically I am interested in doing Computer & Electronics Systems Enginnering and as far as I am aware Strathclyde is the only uni is Scotland that does this course.
Firstly am I right or is there any more uni's that do this course or similar?
Secondly What is the best uni to do this sort of thing at eg. best reputation, where most employers go etc etc?

Also is there any similar courses like this? And where are the best unis that do this?

Thanks smile.gif Any help would be appreciated!

I'm pretty sure that they're different, hydrocracking is doing it with hydrogen. My teacher mentioned it briefly, but I don't think hydrocracking is part of the course (although I think steam cracking is).


thats ok then, whats steam cracking, lol. I always get mixed up between them all?

barcelona is a brilliant city, probably one of favs if not my fav. Sagrada familia and park guell are amazing. So is La Ramblas, the big man street with all the trees! Night life is good too.
