Without reading the other responses (sorry), here's my response.
1. Mostly true. One of the ways Aspergians were differentiated from people with 'classic ASD' was by IQ (which was, for AS, average and above). However...
2. There's no true measure of human intelligence, just like there's no true measure of empathy. IQ can be useful in applying for services, etc., but if your IQ is average to above average... it really doesn't mean much.
3. Referring to (1), notice I say "were differentiated". The DSM 5 no longer classifies AS (or PDD-NOS, for that matter) as an official condition. Everything's just "autism spectrum disorder".
4. And, finally, IQ tests online are almost always unreliable. You need to be evaluated by a professional in a clinical, unbiased setting.
