I tried to search through the SDN for comparisons between the Achiever scores and actual DAT, but didn't find anything. Can anybody tell me how good of an approximation the Achiever tests are to the actual test? Especially for the PAT, QR and bio. PAT has been hella hard. I don't know if it's just me or what. I've been scoring high 20 on Kaplan tests, but in achiever they have been 17. Starting to panic...
