i did the test to know what i can do. so if i scored 125, i can study programming? i also got 27 on wonderlic. what is factual however is that the WAIS i took and they use in PL is outdated
As I previously noted, I can't really give you specific advice on how to interpret your test scores. I can only answer general questions about psychological testing (and other topics in psychology!).
Based on my understanding of the American Psychological Association's Ethical Principles and Code of Conduct (Section 9.01: Bases for Assessments), I can't give you any specific advice about how to interpret your test results, since psychologists should only "...provide opinions of the psychological characteristics of individuals only after they have conducted an examination of the individuals adequate to support their statements or conclusions." However, I can offer some thoughts that would apply to *any* person in your situation.
A discrepancy between the scores from two measures of the same things is, by definition, measurement variability (a.k.a., measurement error). Measurement variability is ubiquitous in science, but is especially common in sciences that measure abstract constructs, like human intelligence. The two scores that you reported are each imperfect measures of some true score that reflects your actual intelligence. This does not mean that one score is correct and the other is incorrect, but rather that both scores are at least somewhat incorrect (w/r/t what your intelligence really is).
Measurement error can arise from a variety of sources. Some of these can be characterized as unsystematic (a.k.a., random), if they occur inconsistently across different tests, test-takers, or test-taking sessions. Sources of unsystematic measurement variability could include differences in attention or motivation that occur between different test-takers or differences in the intensity of environmental distractions that occur between test-taking sessions. These sources are unsystematic, in the sense that they aren't associated with the variable(s) that is(are) being measured. Perhaps on one of the two test-taking situations you were more motivated or distracted than on the other. To the extent that these differences weren't associated with differences in your actual intelligence (e.g., the fact that you were more distracted, during one session than during the other, doesn't mean that you were actually less intelligent, during that session!), they would be unsystematic.
Some sources of measurement variability can be characterized as systematic (a.k.a., non-random), if they occur consistently across different tests, test-takers, or test-taking situations. Sources of systematic measurement variability could include differences in the types of questions that are asked in the different test-taking situations. These sources are systematic, in the sense that they *are* associated with the variable(s) that is(are) being measured. The two tests that you reported, the Wechsler Adult Intelligence Scale (WAIS) and the Raven's Progressive Matrices (Ravens), measure intelligence by using somewhat different questions. The WAIS has multiple components (including one that is based on the Ravens!) and measures several features or dimensions of intelligence. The Ravens has only one component (lots of matrix problems) and measures -- at least in a direct sense -- just one feature or dimension of intelligence. To put this simply: the WAIS measures a mix of different aspects of intelligence, including fluid intelligence (how good you are at learning new things) and crystalized intelligence (what you are already learned); the Ravens measures just one aspect of intelligence, fluid intelligence. Again, this does not mean that one score is correct and the other is incorrect, but simply that two different measures of your intelligence, each of which is based on somewhat different types of questions, don't perfectly agree.
And again, I can't give you any specific advice about how to interpret your test results -- I can't tell you that one score is right and the other is wrong, or that one score is "more right" and the other is "more wrong"... Researchers and clinicians have different theories as to what intelligence is and how it can best be measured. And for any one person (you, me, anyone else...), it is pretty-much impossible to make strong claims about which measures of intelligence are correct -- outside of unusual situations, in which we are sure that one measure is almost-certainly bad (e.g., the fire alarm in the building went off, during one test-taking session, but not during the other!). The important thing to remember is that there is *always* variability in measurement, so you should think of any one test score as an imperfect indicator of whatever it is supposed to be measuring.
As I previously noted, I can't really give you specific advice on how to interpret your test scores. However, I can agree with the basic point that (assuming appropriate administration, scoring, and interpretation) the WAIS is probably a *better* measure of general intelligence (“little g”) than the Ravens. It’s probably better, in the sense that it is a longer test, with more items than the Ravens, and is thus is more likely to be reliable. In general, tests with more items tend to be more reliable than tests with fewer items. It’s also probably better, in the sense that it is made up of a more diverse set of subtests than the Ravens. The WAIS probable captures a broader range of content associated with little g than the Ravens, which is captures just one type of content (inductive reasoning with symbolic relationships).
It’s important to remember that little g is an abstract construct that can’t be measured perfectly, with any one test. Rather, it is can be extracted from the relationships between scores, on multiple tests, using statistical techniques like factor analysis. It makes sense to say that the WAIS is correlated with little g, if we remember that we are talking about the relationship between a test score that is thought to measure a construct (the Full Scale IQ Score of the WAIS is thought to measure general intelligence) and a factor score that describes a construct that is measured my multiple tests (little g is - by definition - the factor that is common to all measures of intelligence). Again, the point is that there is not a perfect measure of little g that can be used as a criterion to evaluate different tests of intelligence.
And *even if there was* a perfect measure of little g, it’s important to be careful about interpreting differences between the magnitudes of different correlations. If the correlation between the WAIS and (some estimate of) little g is .95, while correlation between the Ravens and little g is .80, it certainly *seems* like the WAIS is more strongly associated with little g than the Ravens. However, the difference between a correlation of .95 and a correlation of .80 may not be statistically significant, and we shouldn’t assume that it is statistically significant, without formally testing this hypothesis (note: I am pretty sure that I cover the procedure for testing the difference between two correlations in one of my statistics lecture).
You may already be familiar with the concept of statistical significance. For the purpose of our discussion, a statistically significant difference is one that we would expect to see *only very rarely (typically, less than 5% of the time)* in samples of data that are drawn from a population in which there is no difference between the two parameters (in this case, the two correlations). The point is that it may seem like there is a difference between a correlation of .95 and a correlation of .80, but we may see such a difference (or one even larger!) in some samples of data, *even if there really is no difference between the correlations in the population of all possible data*. Again, if we want to interpret this difference, then we should probably subject it to formal testing.

what are your credentials anyway
I have a Ph.D. in clinical psychology.
can u explain why i scored 125 on ravens advanced and 100 on wais??

i read WAIS correlation with g is 0.95 , while Raven 0.8, so WAIS is more accurate

well then its impossible to know my real iq! i can only know from experience??
