Hey! I personally would forgo showing the GRE scores, especially if your new ones got you an interview. Instead, I would rehearse common questions such as "why did you pick this school" "how would you contribute to the grad program" "any research/specialty interest" etc. Also take about any cool outside experience/research you've done that you'd like bring to their program. This is your time to make yourself look GREAT! If you have to, lightly mention how you've improved on either your GPA or GRE, but they already have the numbers from your application. Remember, numbers don't make a good SLP. You can have a 4.0 and be as dull as a doorknob. They want to get to know you and put a face behind the paper. Make that personality glimmer!!! Good luck!
