transfer

I have over 70-80 credits from lonestar and Tamu. My lonestar gpa was 3.5 and my Tamu GPA was 1.75 I had a really bad semester and failed most of my classes(tamu) so I was suspended for a bit. I have since took a year break and wanting to enter U of H with biology major. What are my chances. The classes I failed were science classes. I was in an abusive relationship at the time but have since opened up to my family and feel like a new person. I do have volunteer hours but idk how good that will be.
