Hi, i just started learning topology( 2nd year undergrad). In class we use course notes made by retired professor 30 years ago. In lectures professor uses those notes but she doesnt write anything on greenboard. She just reads (orally) and sometimes writes one example on greenboard. In notes (old professor asummes big mathematical maturity), there isnt one proof done(fully), always it is easy to show, it is trivial, it is obvious. Even the notes are confusing, for example if we have a family of sets, professor writes as B (like cursive but not that much), then elements of that family as B, and notes are handwritten so its hard to spot the difference. This happen a lot , or family of sets as Z, then sets of that family as Z, (but little dot on the last line of Z). Current teacher reads notes and sometimes in the middle of the proof she just starts doing her own proof, everything orally. There is no pictures, just text, no motivation , nothing. There are 6 students in this class but everybody has problem, we dont understand anything (i mean we understand some stuff but not enough). Unfortunately i go to the university, where if we complain we could only get in trouble.
