Question for Big Three Gads who Went on to Grad School

[retro]

Most grad schools will want all of your transcripts. They will calculate a cumulative GPA based on every school you've attended.

That's a problem. So, my previous GPA from my previous college was in the 1.95 range. My HS transcripts reflect a very similar 1.9x GPA. I need desperately to counteract this as this isn't a true reflection of my capabilities.
In a nutshell:

• I have ADHD/dyslexia with an IQ far above average. The ADHD is well managed now, but could not be at the time. Also, absolutely nobody knew what to do with me given that I am what is now called a "twice exceptional."
  
• My HS's idea of special education was to treat me as no different than some kid with a low IQ and just lower the bar, pass me, and not really make genuine attempts at helping me actually remediate my issues.
  
• This of course did nothing to prepare me for college and untreated ADHD had its effects on other subjects.
  
• My college flat out refused to accommodate my dyslexia's impact on my math skills. Yes, it's illegal. Yes, they got away with it because I didn't have the legal resources to push back. It has been 20 years, I can hardly hold them accountable now.
  

I have no real choice but to own that. I can cry about it or do something about it.

Ideas that have crossed my mind:

• Compensate by getting three BS degrees, even if they're all ACE/NCCRS credits.
  
• Study for the SAT/LSAT as an adult, with the proper accommodations and aim very high.
  
• This is perhaps "unicorn country" but, most schools have a policy of accepting the higher GPA when a course is failed. Turn that policy on its ear and go take a GED test as a one-for-one counter to my original HS grades.
  

I'm open to suggestions here, lots of them.
