No. I will pass. Too many questions.

Hey everyone my daugter is in 5th grade and she has a problem of the week i need to help her but i cant figure it out the question is

Students in Mrs.Langs class are either 10,11,or 12 years old. David entered his age into a calculator and multiplied it by a three digit odd number. The result is a number that has the digit in to ones place. How old is David?

Im not sure cause i dont quite get the question.. But thats my final answer becuz

10 times any 3 digit odd number equals something that ends with a 0..so the answer could be 10 cuz 10 ends with a zero and it says the result is a number that has the digit in to <–(??) ones place.

Confusing but i think thats the answer…
Wow it must be hard if even a parent doesnt know the answer.. 0.0

## Why are so many IQ tests math or word problems?

One can solve math or word problems using his/her natural abilities PLUS knowledge. Those tests are highly inaccurate when one does fail because, let’s say, lack of geographical knowledge while other succeeds cause he knows techniques how to solve math problems fast without using calculator.

Why are such „IQ“ tests still up and why they are so many? Now i don’t wonder that one can „learn“ to make IQ tests better and better.

As example: English is not my native language and i dont know US states so obviously i do fail when i must find odd word out from words that i do not understand or i must form a US state name out from given letters while i do not know such a state.

Do we test IQ or knowledge?! There is IQ tests out there that does use just symbols or numbers. They must be mandatory cause now my IQ test is something between 100-130 depending a test, and this is not logical…this is plain silly.

Real IQ tests are different because there are different theories on what „intelligence“ is. For non-native English speakers, a test like the Stanford-Binet or the CAS (Cognitive Assessment System) are probably better than a WISC/WAIS. Most intelligence tests are biased towards middle class North Americans, but some are less biased than others.

Online IQ tests are made-up. There is no standardizing and there is no theory behind their measure of „intelligence.“ Don’t put any weight in results you get online. Go see someone who is trained to administer *real* tests. If you go to a registered psychologist (one specifically trained in psychological/psychoeducational assessment) you will get valid results. They will probably choose a test that is good for you.
