exit exam/boards

I am currently a nursing student scheduled to graduate in 5 weeks..i am currently freaking out. We have been taking practice ATI tests to see our chances of passing our exit/boards.. i have not been doing to well on these exams..usually scoring in the mid 60s...i feel like my probability of passing is slim to none..i dont know what else to do..i have all the ATI books and have been reading them constantly, doing at least 50 NCLEX q's a night in the Saunders book..any words of wisdom or suggestions?!?!
At my school as long as we were making 60/65 on the practice ATI tests we were doing good.
