Retake GRE for Cognitive/Dev Psych?

[ed2122]

My scores from last year (when I only had about 2 weeks to study after deciding to apply to grad school) are 166 verbal, 153 quantitative, 4.5 AW. I completed my undergrad in 2007 so I was (and still have been) out of the academic game for a while. I am happy with my verbal, not too concerned with my AW, but worried about my quantitative score. Should I retake the GRE? And if I do can I just re-use my study books from last year?

 

I have a strong GPA, some research experience in a lab and a undergrad research paper, and last year I interviewed at 3 schools, waitlisted at 2, but ultimately wasn't accepted anywhere. I am planning to apply to schools like JHU, Harvard, UPenn, Delaware for cognitive or developmental psych (it varies by school). I am presenting a poster on my undergrad reseach at a conference next weekend.
