Yeah, I graduated with a 2.9, which hurt in some jobs where they wanted to see a stellar academic record for jobs I knew I could do. They automatically assumed that I was either too dumb or too lazy to do the job. That’s not always the case, but it stung to see how my past mistakes caught up with me.
I would contact a counselor in the office of a B-school you might like to attend one day and ask what the best way would be to mitigate a poor undergrad showing. And when you do eventually apply, put in your essay how you’ve learned to do better and to apply yourself more from having learned from the outcome of your poor cumulative GPA as an undergrad, so you’ve done taken more initiative on your job. Admissions committees look for improvement over the course of the time in between. They’re aware that everyone isn’t some academic rock star, or hardly anyone would qualify for these places.
