^keep in mind, with am1/2 we do have 4 lectures a week instead of the regular 3, so over the 2 subjects, we had about 24 more lectures than if you'd taken two of the subjects and only 12 less than if you'd taken all three of the subjects.
If anything, from speaking to friends who took calc2 and linalg, I actually think that we may have covered those two subjects more thoroughly than they did, calc2 especially. Barry proved a lot of the theorems (such as l'hopitals rule) for us and went into scaling factors for ODEs that the calc2 students did not. and Paul always tried to throw in a bunch of applications for linalg (google pagerank, standing waves, error detection and correction). i think we did some minute stuff in am1 that wasn't covered in linalg as well. I may be wrong, but i don't think the cross product was covered in linalg for example. So if anything, I feel like we actually got a more rigorous and thorough look into most topics from doing am1/2.
the only thing i felt like we really compromised detail for was the algebra/arithmetic stuff from calc2. the lecturer went over some of the integration techniques in lectures and then asked us to learn the rest from the worked examples at the back of the notes and through doing assignment questions. From looking at past exams, we also skipped one of the minor topics from real analysis, but i don't think it's a huge deal. it was the one where all the questions were like, "rewrite this statement in mathematical symbols" or something like that;;;
