Keep up the GPA in your grad work, and Study study study for that MCAT. Your score will make a big difference to your school list: 505 would be good for DO and lower-tier MD schools, with other MD schools being “reach”. 510 sets you up for more MD schools, and 515+ would give you a chance just about anywhere. Adcoms understand that working full-time and getting a 4.0 are not always compatible.
