If i'm remembering correctly, like you, i had a poor GPA in my first bachelor's (psychology)
My GPA for my second bachelor's was a 3.75, GRE: V-159, Q-154, W-6
I was accepted off the waitlist to USF! So excited. To the pp who was asking (since we are in similar situations), I think the poor area of my app was experience/volunteer so maybe work on that (unlike me) while doing your 2nd bachelors.
I just completed the 2nd bachelors at USF with a poor GPA in my first bachelors (also psychology). I have a 3.75 in my second bachelors. Soooo hopefully in a couple days here I can let you know how that's worked out for me (whenever we hear back from usf). You may want to also check out the video on the usf slp grad program page, it talks about how they consider csd coursework gpa over out of field.
