I think these are great scores and good going Homer.
I remember not liking science or chemistry at all and did what I could to avoid it. Of course in college, Chem. 101 was required....none of it made any sense and I just couldn't reach the point where it "clicked"; finally spoke to the instructor, who was very good by the way, was told if I really tried and showed up for every class he would pass me with a C since the class had nothing to do with the career I'd chosen. Mission accomplished.
