The MCAT requirement is evolving so I would speak to the Pathways office directly about what that requirement would look like for next year. There are several milestones you must meet before matriculation is recommended, both academically and professionally. It isnt enough to pass the blocks although it’s a requirement so I hesitate to say you’re “guaranteed” acceptance. You have to be proactive with how you spend your time, especially between the two high-intensity blocks. Take advantage of all learning opportunities and put your pride to the side and listen to feedback. That part is especially crucial. That being said, a Pathways student NOT matriculating the following year is a very rare occurrence, but it has happened. Bring your A game from day one, the same you would do if you were an MS1 and you should be ok!
Good luck!
