Have you looked into what your program says they are looking for? I am applying to English programs, so most schools say I don't need a Q score at all. Only verbal.
If you want to retake it, I third the Kaplan book! Really helped me. I had the 2016 one and my score raised 8 points in verbal in a month using that book to get a handle on how to answer questions, and what vocabulary comes normally. Good luck with whatever you decide!
