In summary, the conversation discusses which undergraduate pure maths subject is the most challenging. Some participants mention different factors such as the quality of teaching, personal interests, and the difficulty of different topics within a subject. The majority seem to agree that analysis is the hardest subject, with topology as a close second. Some also mention that the presentation of the material, as well as the textbook used, can greatly affect the perceived difficulty of a subject. Combinatorics/graph theory is also mentioned as a difficult class for some participants.
