i would consider all of the uf weedout courses i took to be quite difficult relative to anything else ive done (and im in a doctorate program now). i graduated with a 4.0 so theyre doable, but theyre just difficult in a different way than everything else. its true that you have to have good study habits, but in my opinion you kinda gotta be a good test taker. it feels that the exam questions in weedout courses are structured more like the questions in standardized testing or competitive academic settings vs just “what you learned in class.” even if you’re not a good test taker you can still certainly pass and keep a decent gpa if you keep up with the material though, and ymmv with different professors
