Something Time teaches you:
To progress/succeed we need to know more than we already know at any one time.
Unless you ask the questions, nobody knows you need the answers.
If nobody knows you need the answers, nobody gives them to you.
If you don't get the answers to the questions you need to know... status quo

.
Sounds crap - you sound like you're a major league down brother at the moment! What Uni are you going to?
My advice being a lecturer is yes to asking the lecturers heaps of questions - especially at the start, once you get a feel for how it all works then become a lot more independent.
When I was 18, I think that I saw having to ask questions as a sign of weakness, but as time has gone on, I've started to view it as something which is beneficial and as Liz says, if you don't ask then you don't get. I guess it's down to being more confident with age etc.
@ Dave - going to UWIC in Cardiff.
Anyway, new day, new game. The sun is shining (again

) and we have an away game on the coast, hopefully not too far away from the beach.
