Does medication increase IQ? | ADHD Information

I've always struggled with math and I think it's due to me
just wanting to know what the answer is right away, instead
of carefully working out how to solve the problem.
I like to do IQ tests and having almost no math ability
makes it hard to feel positive about myself.
I was wondering has anyone ever had a problem with learning
and after medication done much better?
Not all in the IQ test is math...there's words and pictures and puzzles too!  Hopefully you can feel good about your scores on some of these other tests...

I took some of the tests both on and off medication, but the difference in scores was not significant... except for the CPT test of continuous attention.

Thanks, I guess I'll never be good at math. I do a lot of
revision but 1)It gets boring and 2)I soon forget what I've
learnt.
