OP - what grade did you get - or will you be getting for Org Lab? If it is a passing grade, and the rest of your GPA is good - I would say dont worry about it. It is one or two credits - in the grand scheme of your entire transcript - and its a lab.
If you didn't fail - move on to bigger and better classes (Org Lab blows)
If you did fail - I would retake it - but, as another poster has already posted - you need to ascertain what happened with the lab. Org lab, while very boring, should not be stressing your academic muscles. It requires organization and effort (and a decent TA never hurts) - if this class was causing you headaches - just wait until you get into Drug metabolism with clinical cor. You have more diverse, intricate information thrown at you, and it comes way faster. Do some soul searching - and if you decide to stay the course (which I always feel is the best course) - do so with conviction.
