Discouraged? You wanna hear about "discouraged?" I took a course in atmospheric physics, which was taught be a Dr. J. V. Geschwendtner. He was Austrian and a meteorologist for the German Luftwaffe before WWII. He left Germany, went to England, and ended up working on the Manhattan Project here in the USA. That guy's mind operated at light speed compared to our feeble attempts to understand advanced physics. Well, all three of his classes were taking the midterm exam in one big room. Looking at the exam, the printing might as well have been in Greek. It was like hitting a wall at 100 m.p.h. My mind went blank. Almost nobody had a clue about where to even begin. About half-way through the alloted time, one guy balled up his test, threw it into the air, and left the room. Well, the highest grade out of the three classes taking the test was 34. Yup, 34.
P.S. Dr. G. had us taking a daily quiz (which he pronounced as "kvizz") for the first 15 minutes of the class. The quizes became so difficult after the first two weeks, that we would show up at 7:00 a.m. for the 8:00 a.m. class.
Remember, all is not lost...yet.
