Nice one, thanks. I completed year 1 of an HNC in electronic and electrical engineering at day release in 2010, so once this module is out of the way i can get on with stuff that i can choose. I have already passed analytical methods, electrical principles and digital and analogue circuits so if you guys need help when you get to them give me a shout, obviously the questions will be different but i'll do my best, i hated calculus though!
