Here's an oldie-but-goodie New York Times piece by Dr. Pauline Chen on medical student grade inaccuracies. In reading the article, medical students should reflect on how important the quality and content of their letters of recommendation are for residency applications, especially in the setting of medical school grades that may be inflated or faulty. The 2020 NRMP Program Director Survey (which is the most current version) supports the importance of letters, as well, with statistics. Make sure your letters are very strong; remember that mediocre letters should not be a part of your residency package.
