Testdex is an index of the best personality and intelligence tests I can find. All tests listed here are free and don't require any registration. A few may offer an additional report for a fee (which I recommend you don't get) but those still give enough free results to merit inclusion on this index. If you find a test here that does not meet those standards or that you don't think belongs here please report it. If you know of a test that belongs here, submit it.
