Hi, I have been out of school for 3 years. I have 3.4-3.5GPA, 18/18 DAT, and tons of volunteer and research experiences. I have co-author in 3 journals. Also, I have the great reccomendation from research professors! I am currently taking grad. courses in biology and have a 3.5GPA. I want to get into a top research school, such as Harvard, UCSF, Columbia, and UPenn. Do you think I have a shot? Do you think I need to improve on my DAT?
