Hello. How closely do you think the results you achieve in a course-- in the tests and exams-- are related to your understanding of the material? Of course, there is some correlation, but how good is it? I mean, perhaps all the problems you come across in a test are taken from your textbook, so you've seen them already, or perhapsthe material you were taught was very artificial. Certainly, if you're doing poorly in a course it's likely you haven't understood the material. But say you get 85% on a test, and someone else gets 90%, does that necessariy mean they understand the subject matter better than you? To put it differently: is it more important to do well in a test, or to understand the subject the test is supposed to be testing you on? These may not be the same thing. But are they closely related? How closely? It just may happen that someone else 'sees' the solution where you haven't; does that mean they understand better? Maybe you take a little longer to get to the answer, maybe for a bunch or reasons: maybe you're a bit more rigorous and need to convince yourself more, maybe when you do get it you have more insight. Maybe you're just not as smart. What do you think?
