retake the TEAS?/??

I am trying to decide if I should retake the TEAS version V test. I apply for nursing school in May for a fall start. My school takes your overall Teas V score and adds in points assigned the letter grade you got for A&P, Eng Comp, and Psych. For example:

Earned grade point calculation (GPA): Class grade times the number of credit hours

(A = 4 points; B = 3 points; C = 2 points)

Anatomy and Physiology ( 5 hours) maximum points 20

English Comp I ( 3 hours) maximum points 12

General Psychology ( 3 hours) maximum points 12

Maximum Total Grade Points 44

Plus

Admission Assessment Exam - Highest possible composite score 99

Highest possible applicant score for ranking 143

Here is how mine breaks down: I got an 80 on the TEAS, and 41 points for classes ( if I get an A in A&P...it will be 36 points if I get a B) for a total of 121 points. This number is what they use to rank you for the 56 slots in the program. There are usually about 250 apply. Around 130 have taken the TEAS and only 9 have gotten above an 80. So.... I have the option to take it once more and try to score higher to raise my overall ranking score... or I can take my chances. The dept says average TEAS V scores have been mid 60's to low 70's.

Would you retake it??
