I think there are pros and cons to both systems. I feel that it certainly streamlines the process for people who already have an inkling that they are going to pursue medicine in the future but I feel that it comes at the cost of exploring other experiences, youth, and just overall maturity level.
Medicine is a physically and mentally demanding field. I think that having a certain amount of life experience and maturity that only comes with age can give you some level of resilience.
While the more indirect admission system can take longer to complete, I think it works to the benefit of people who may not have realized they were interested in medicine until later on. The age demographic for my class is quite broad, with some members being in their 40s. That level of flexibility and that understanding that not everyone has that epiphany at a young age normalizes the experience. In addition, their added wisdom and experience becomes quite apparent once the educational journey begins.
