Hi all, first time poster, been registered for a while though. so i just finished the 3 semester introductory courses that my school requires of all physics major (so i'm a sophomore). i am a bit worried though because in physics 3 the class average was 73 and even though my average was an 82 it is a non-curved class so i have a B-. now, i have a strong desire to learn physics and to study it on the graduate level and to bury myself in it as deeply as possible. if i show an upward trend in my upper level classes can i set my sights as high as possible? i do research with a rather well known soft-matter physicist who wrote a leading textbook on the subject and attend a very decent private university. i mean it is introductory physics. tell me like it is, i do not want to be deluding myself.
