As long as you've proved you can handle it now, I'm sure you'll be fine. I didn't work as hard in undergrad and had an overall ugpa under >3.0.. I look at it as a lack of maturity at that point and find no excuse in it now. Took the past two years off to work full time in a lab and have been working on my MS in mol.bio and I've significantly made a 180... Not to mention I'm way busier now then I was prior to my graduation in 2013. I've submitted my applications for the '16 cycle and so far have received an interview within a week or so after verification... (Still waiting on a committee letter so that's delaying some stuff) ..It's possible, just don't make excuses for your mistakes and learn from that.. I'm sure they'll see the change you've made... Focus on the positive and what you've learned about yourself during the process
good luck!
