I am a non-trad with US undergrad Biology (cgpa 3.3ish with few repeats) and graduate Epidemiology degree (cgpa 3.7). Currently on student (F1) visa, but likely to be a permanent resident in couple years if things go smoothly. Now, coming to my question I have been planning of taking few (4-6) biology classes over the course of next 1-2 years. However, I am wondering which (grad or undergrad) level biology courses I should take if my ultimate goal is to apply med school in future? I will likely to get tuition reimbursement from work if I go for grad certificate in micro/biology, but think comparatively undergrad level biology classes will help my low undergrad GPA and med school chances than grad certificate. Need expert suggestions. TIA.
