Computer vs. paper vs. ATI online practice

[honeybadgerdontcare]

I see where a lot of people have gotten better scores on their actual TEAS exam than they got on the practice forms A and/or B. I also see people saying that the online version is harder than the paper and pencil version. My question to those of you that have taken both the practice and real TEAS is: how much better/worse have you scored on the actual exam, AND was the exam you took the computer or the paper/pencil version? After seeing both the online practice tests (and getting the same score on both even AFTER serious studying) with questions not covered in either the ATI, McGraw-Hill, or Kaplan study guides I'm having some serious anxiety issues and I normally don't have those with testing. I take the computer test Friday morning, and the program I'm applying to is insanely competitive; the average score for people to even get an interview is around an 80% AIS. Is the real test that full of random science questions that AREN'T covered in any of the manuals? I've also gone through the entire sticky thread. Science is really all I'm worried about.

Thank you in advance :)
