Did I ruin my chances for grad school?

<p>I didnt do well my first two years of college. I was dealing with a lot of personal issues, including the death of a loved one, I just had a low self esteem, and I felt depressed, though it was not professionally diagnosed.</p>

<p>I pulled a lot of C's some B's and a few A's I also failed and retook 3 classes (chem1,2 and ochem1), and I have 2 W-pass</p>

<p>After my second year I managed to turn my life around and I started getting A's I am studying hard for the GRE. If I get good grades for my last 2 years of college, and I get good GRE scores. Do I have a chance at getting into graduate school? I am a biology major, I want to pursue a degree in public health.</p>

<p>Did I ruin my chances?</p>
