3.42 GPA, 503 MCAT (retake?), URM, aiming for MD/PhD

MCAT: 503 (127/121/128/127) GPA: estimated at ~ 3.42, it may be higher though but definitely not lower — would need to calculate since I attended two institutions. ECs: 1000+ clinical hours 600+ clinical volunteer hours 200+ non-clinical volunteer hours 1-3 years of research (depending on how long I stay at my new research job) 1 publication URM: Mexican American My biggest concern is my MCAT (especially CARs). Do I have a chance or should I retake for a Top 20 MD/PhD program? Please... 3.42 GPA, 503 MCAT (retake?), URM, aiming for MD/PhD
