this question pops up time-to-time on sdn, and every one gets in a circle and convinces themselves that yes, there's less orgo, or less physics, or more genetics, and that becomes the conventional wisdom just long enough for a cohort to get their faces melted by four difficult orgo passages on an individual test. Then everybody shrugs and we go six months till it's time to lather-rinse-repeat. Just learn the material for christ's sake. Success on the mcat isn't some exercise in game theory. If you know the material, as indicated by your practice fl scores, you will do fine on the exam. If you decide to skip orgo prep, i would guess that your competition for acceptances will want to thank you.
