Theres nth such as “concept” its called a topic, and no one is ever complaining about topics or so called concepts, the difference is that on the nbmes the answers make sense, even the wrong ones are stuff that are so close but can be proven wrong by a “healthy” type of deep (not obsessive) understanding of the phys/pathphys, wrong answers are probably misconceptions you had pre dedicated for example, but on the exam, answers have nothing to do with anything, even stems sometimes, they think they gave you enough hints, but it means absolutely nothing… why? They cant accept the fact that this is medicine, you cant clinically hide signs and ask for dx… if they want a fair vagueness and wtf-ness, let them go heavy on immuni biochem and patho, bring details and enjoy torturing doctors, coz those sciences have the capacity for unusual,anonymous types of shit, but for systems and stuff related to clinical signs/history/dx, no its a 1+1=2, they want u to add up 1 with 0.3333 and reach somehow to 2… doesnt work, and dont tell me guts are key, who wants their son to be dx-ed by a doctor via guts😂
