Does anyone have slow processing speed (where it takes you 5x longer to read or complete school assignments), and if so, does it affect how well you did in classes or how many credits per semester you could take? How do you cope with it?
I'm currently in school trying to get an associate's degree, but I'm so slow that I can usually only handle one class at a time. I'm well aware I will be in my late twenties or early 30's (I'm almost in my mid twenties already) by the time I finish, and I don't want to be stuck in my parent's house for the rest of my life.

I am unable to work and go to school at the same time.
Generally whenever I talk to anyone about this, they seem to get the impression I'm coming up with excuses, or they don't understand and tell me to basically to just do all work no play (thing is I WILL work all day and still make hardly any progress).
I failed my first try at college even though I had a great support system from my friends. My friends didn't understand why they started at the same time as me and yet finished in half the time even though I was hard at work the whole time. For about half a semester I got my friends to work with me but after a while they got more efficient and I didn't so they stopped coming by. I don't really know what to say except to work ahead. By the end of the first week you should be half way through the material needed for a the midterm and treat "breaks" as opportunities to get ahead.
