Coming from a small school, college life was in itself huge transition - too many other opportunities… dances, girls, alcohol, girls, concerts, girls, activities, girls… and then was hard going from the small HS local teachers to Middle Eastern assistants, comprehending that Profs and Assistants were not there to teach in the same manner as HS teachers, and study habits. But as to specific class… heck, highest HS math had even offered in my rural area was geometry / algebra, so going into Calcuseless was a bit of struggle, as was Physucks. Elect. Engineering Circuits was hades - mainly due to my own ineptness,,, and learning that my mentality is more of a researcher / scientist, not an engineer that memories this and that. Really, I could not care less that a transistor or a resister or a reostat or a whatchamacallit went here or there… I wanted to know HOW and WHY these devices worked. Thermodynamics was difficult, mainly cause the Prof was an egotistical condensenting [sp] shmuck. But somehow graduated with a Metallurgical Engineering BS, with a 3.7 in my major, and couple minors [Geology and History], and just 1-2 classes away from another [Physics]. LOL - first Physics, the classical Newtonian, I could not stand - flunked / retook it three times

Dumbest class - who gives a frig that a mass of 'x' going at a direction 'z' with velocity 'v' and angle 'such-and-such degrees' will land where? But the modern Physics, with the optics and magnetism and quantum stuff,,, that is great stuff. Interesting how different classes / subjects were favorites or hated ones by the replies here.
