Congratulations, don't be discouraged, many students I have worked with through the years have struggled with PAT. Your GPA counts too and yours is high which proves you are a hardworking and serious student. Most schools would be ok with the 16 in PAT especially with you high GPA and other DAT scores, but if you have a dream school in mind you might want to contact them with your stats. I would not retake the exam. Wishing you the best....Nancy
