I have two failed attempts at college behind me. Both attempts, one in 1994-1995 and the other in 2000, were before I knew that I was autistic. Tests were difficult, and when I was taking someone outside of one of my special interests it was even more difficult to get through.
Now I'm trying again with accomodations. I get to take tests in a quiet room and I get extra time so I'm not rushed (worrying about how much time is left can really slow you down, even more so when you sometimes have to read a question several times to understand it.) This didn't slow me much in high school but, as my AP teachers noticed when I bombed my AP tests, sometimes it did.
Since I'm working full time, I'm going to school part time (only one class at a time.) As a parent and the main bread winning of the family I can't afford to cut back on hours at work or take an educational leave. This quarter I'm taking a math class (with many more in my future.) When I took math in 2000 I didn't do so well. But this time, at about halfway through, I'm holding at about 92%, which is much more in line with how I did in high school than 2000 was. This class doesn't count at all though, other than to get me into pre-calculus, which will then get me into the needed calculus.
And for some reason it's not a surprise that even though the disability center director tries to meet with the autistic students at my school regularly as a group there's been no success at getting us all together so far this quarter. Maybe we'll meet before the winter break, maybe not.
