I would agree with @cobrat on this one. If anything, post-bacc programs are more costly than ever, and intensifying competition for medical school admissions makes them risky for many students.
Also, most schools have some GPA requirements for post-bac students that are similar to those for transfer students and the requirement for a pre-health post-bac could be a 3.0 or higher in all attempted science courses and overall.
I did notice when I was in college that many pre-meds loved to brag about how easy they found their classes, and how little they studied, perhaps to deflect the stereotype of the pre-med grind who is not “naturally smart.” And, some really did seem to breeze through tough classes of all types without losing sleep or breaking a sweat, while I was aware that others worked long hours and avoided classes outside of their comfort zones.
