I was wondering if anyone out there could please clarify something for me. I am an adult student, now taking pre med classes...and am doing very well. However, my undergrad GPA is less than stellar and I want to retake a few classes to get that GPA up. My question is: HOw does this work??? Do I retake a the SAME class I did poorly in...and the new grade gets substituted when I calculate my cum GPA on med school apps??? OR...I just take ANY class at all and do well...and just average it in with the old??? HELP!!!! Any help would be appreciated!!! thanks!!
