Dr. Dick, thank you for your reply. You know, I have taken college chemistry before, but changing from one university to another (due to PCSing)I had to repeat this chemistry (101). If all the professors were as good as the one I have right now, I would easily succeed . I mean this professor explains chemistry as if we were five years old, hahaha. Well at my age I guess I should just consider a B.S. in chemistry. I guess for me that would be satisfactory. Living in Europe (Germany) for five years put a stop to my studies, yet I don't regret it. I love Europe and spent my time very well traveling to different countries that borders Germany and even England, Spain and Sweden. Hey, I can't complain about that. Luckily now here in good old Texas, and by the way, howdy, I have the opportunity I've been waiting for.
