When I was a first year undergrad, we were invited to sit-in on a tutorial of the final year students, who all seemed so very clever and erudite and used loads of big words. I was completely in awe of them and wondered if I would ever be as confident or knowledgeable as they were; I was sure I never would.
I feel a bit like that on this thread
Gearing is something I need to mug up on. I wonder where to start.
