Grades Vs. Potential

Hi, I’m going to LA Tech and obviously am going through the rush process. I haven’t registered entirely because I am quite worried about my grades and if I would be cut because I don’t meet most gpa requirements of the houses. Honestly my GPA doesn’t reflect my work ethic at all and is low because of my first two years of high school, my grades the last two years were actually pretty good. However, my resume and involvement in high school and volunteer work is excellent. What would people that are already in Greek life/ gone through rush suggest I do? Would the houses check my transcript and take my improvement into consideration?
