I don't think you're screwed, necessarily, but you may need assistance in certain areas. I see a lot of autistic people writing about how they did really well on one part of the Weschler Adult Intelligence Scale, and really badly on another part. A lot of autistics have good to strong skills in some areas, and deficits to the point of disability in others. Processing Speed is frequently a big problem (mine was only in the 14th percentile, really low). That means only 14% of people who took the test did worse than me (not sure what that is in IQ scale, but it's Low Average). I also did so-so in Working Memory (30th percentile, Average). This made sense--I don't work quickly and my memory is cr#p, and I also did poorly on the parts of the test that had the psychologist giving me spoken instructions or spoken math problems. My comprehension of the spoken word is poor.
On the other hand, I was in the 86th percentile for Verbal Comprehension (High Average) and 95th percentile in Perceptual Reasoning (Superior) because I do very well with written material and visual reasoning.
The whole thing averaged out to a total IQ score of 108. So what does this mean? I have gravitated into a field of work where I can use my strengths (commercial art and website design), but there are things that I really struggle with, most especially things like being on time, disorganization, and juggling multiple responsibilities. You may do well in your line of work, but need help with certain things, perhaps through workplace accommodations and life hacks like reminders, lists, and calendars. I use my iPhone and Microsoft Outlook to set reminders, make lists, memos, Google Maps to keep me from getting lost, and music to keep me calm on my commute and to help me concentrate at work.
