Currently an M1 doing part-time remote work about 10 hours per week. I’d say it’s manageable but I absolutely do not recommend it. I’m personally doing well on exams during a notoriously difficult part of my school’s pre-clinical curriculum, but the days can get pretty long. If anything, it’s forced me to get better about time management. I’m planning on quitting within the next couple months and filling that time with research.
The way I see it, there’s basically no amount of money that an employer could pay me that would make that time commitment worth it throughout all of school. I’m interested in a competitive specialty and the long-term financial consequences of not matching or being forced into a lower-paying specialty are orders of magnitude greater than what I’m getting paid.
