Disagree.
1. It might seem like an unskilled position to a medical student because it comes easier, but there typically is a pretty significant learning curve, particularly for undergrads.
2. It is fairly poorly compensated, but can have a lot of down time depending on the setting, so it's not much of a hassle when you can study during this time. It still typically pays as well as or better than federally-funded work study.
3. It might not look as impressive directly on a résumé, but the medical decision making and clinical knowledge gained, proficiency with H&Ps, lab values, imaging interpretations, drug indications and dosages, etc. make it overwhelmingly more beneficial than MCAT tutoring and sufficiently more beneficial than M1 tutoring (depending on curriculum) for board and clerkship prep. Logically, since boards > clerkship grades >>>>> ECs, scribing is a much better option.
Not just blowing smoke - This is coming from my experience scribing for 2.5 years, 1.5 full-time before med school and 1 part-time during M1, and 3 years of tutoring, 2 in UG and 1 during M2.
Caveat: the extent of the benefits of scribing can be largely dependent on the providers and personal effort. Work fast and act like you want to be there to learn, and most providers will not stop teaching.
