failing courses and retaking them!!

<p>Hi, im preparing for an mba or a dba, but am worried about a few issues. </p>

<p>i currently have a low GPA, but the fact is my school is a very reknowned university and its just really hard to get good grades, not that i didn't put the effort. </p>

<p>Do grad school official take this into account? </p>

<p>Also during my undergrad I have even failed a course but have retaken them in a summer program which is a pass or fail course. I was hoping that as I had retaken the failed course it wouldn't count towards my GPA and retaking a pass or fail course.. it would just totally be erased.. </p>

<p>Would that be possible? </p>
