please help

<p>I am currently a freshmen (first term) in college and hoping to get into med school. I got a 6 in IB Biology HL but still decided to take an intro general biology course (a course i already received credit in because of IB). So far its pretty difficult and there are many concepts that weren't covered in IB. So my question is if I were to get an A- or B+ on an intro class that I already have IB credit for, will it look bad for med schools? Thanks in advance.</p>
