An individual's IQ score may roughly be determined by extrapolating the raw results of tests which aren't designed to determine the individual's IQ score directly (such as the MMPI , the AFSVAB, the SAT and the ACT, among many others). My own IQ score was extrapolated by two psychological professionals from two different MMPI results and by an educator from my annual public-school test results (I think it was a variant of the SAT). I always admit that my IQ score is "about 145" because I amn't certain about the accuracy of the extrapolations even if they were confirmed by three independent professionals.
In other words, don't put too much faith into any one IQ score especially if it is determined by extrapolating other results. Without completing an actual IQ test, an extrapolated score is just an educated guess. After all, some IQ tests are visual, some are verbal, some tests only use abstract-reasoning problems, and some tests concentrate on arithmetic, spatial imagery, reading, vocabulary, memory or general knowledge.
In your specific case, I would suspect that your second IQ score was extrapolated from a multiphasic test like the MMPI (correct me if I am wrong). The disparity between your first and second scores suggests to me that the second score was extrapolated from a test that isn't normally useful for IQ scoring. Another reason for the disparity could be that an IQ test factor (visual, verbal, etc.) simply didn't reflect your real IQ score accurately.
In the end, it is possible for you to pay for an actual IQ test (the University of Utah, or other college, testing center can arrange one for you) for about $200-300 (maybe less). Carb up the day and morning before the test, add a single cup of coffee and scream through the test as best you can.
