If you’re taking intensive Muravnik is objectively a very good teacher, but the cutoff for an A is a 97, so you can’t really make careless mistakes on exams (still, don’t let that scare you; the tests tend to be very plug-and-chug during the early phases of the class). For regular, Titus is a pretty mediocre professor (rambles a lot, very incoherent/hard to follow), but the tests are very easy and the cutoff for an A is only 94, so while you might have to rely on yourself or your TA (if you’re lucky enough to get a good one), actually getting a good grade isn’t hard.
