SDN Members don't see this ad. (About Ads) Your numbers are wrong. The Research Pathway (call it this because it is in no way fast) is 2y of IM, then 4y of Onc (if single boarding) or 4.5y if double boarding. So in the end it's the same or more time than the standard pathway. That said, skipping my IM3 year was the best decision I could have possibly made.
