I've made a B in Organic I, an A in Organic II and a B in Biochem.
Since the first two seem to be the weedout courses, and the last will be seen again in medical school, would the overall assessment be pretty good for those courses ?
It's pointless to be asking this. The interpretation of your scores in these classes can only be made in the context of your entire application. How someone views them is going to be wildly different if you have a 3.0 GPA and a 29 MCAT versus a 3.9 and a 35.
