Learning Disabled, Need Some Advice

[retro]

Hey folks. I have dyslexia. As a consequence my spelling is very poor. My mental math isn't much better. In day-to-day life it's something I can work around quite trivially, thanks to spellcheck and a four-function calculator.

I'm starting from scratch at just shy of age 40. At some point I'm going to need 6 credits in composition. Like a lot of you, I'm going to test out of as many credits as humanly possible. Because of my the effect of my learning disability, I'm afraid I'll blow the written portion of any test just from bad spelling. I already know I'll need some accommodation for my ADHD, extra time.

Obviously, I prefer a pass/fail situation to a GPA grade where my learning disabilities are a factor.

So, my questions are:

1. What are some exam strategies that are likely to work better for me?
2. I realize I could take the Ed4Credit.com or Study.com courses and get credit. In light of my situation, what are the proctored / graded portions of the courses like?
3. Has anyone here ever gotten meaningful dyslexia accommodation in a test environment? I've had terrible luck in this department. "No, you can't have a speller's dictionary... No, you can't have a four-function calculator, etc."
