OAR must be higher than 40 to be competetive.  I have taken the test twice and improved significantly the second time to scores of 5's.  I hope that I will be able to get to the 7/8 level after one more stab at it.  I have never been very good at taking tests.  I hear that it is more competetive now than ever so you need to ace every test and do very well on the PRT.  Good luck.
