Gonna agree with you here. I am not from a top undergrad, but every MED student I have talked to has said the material is far easier, everything fits together in a much more coherent way (like what you are learning is actually applicable) and you don’t have to worry about any ECs if you really don’t want to. The difficulty, so I have heard, is simply a matter of both volume and willingness to study. In MED school, if you are comfortable where you are at then you can stop and not worry too much. Or you can keep going and eek out those ever important points. This is anecdotal and will vary by person.
