College courses require proof of minimal competency in highschool math. It may only be freshman math, be it algebra or trig, but any college wants to see competency in basic math.

The only exception to this are some tradeschool courses, but mortuary sciences requires some chemistry, which requires math. My suggestion is to meet with your counsellor, find out what the minimum remedial requirements are, arrange tutoring and whatever other assistance you can based on your disability (it must be a documented disability: "I suck at math" doesn't cut it) and do what you have to do to pass the class, even if it takes several tries.

This is speaking as someone who aced all of the GED and scraped through on math. ACED the SAT and did OK on math with the help of tutoring classes that ended 2 days before I took the SAT, and scored a 32 on my ACT which woulda been a 36 if it hadn't been for the flipping math. You have my sympathies.

I'm old enough that dyscalculia wasn't recognized as a learning disability when i was in school. I found out I had it when i was in my early 40s. By then, I'd already found out about the various types of calculators, etc., and functioned, but i can't even do arithemetic on paper very well,let alone higher mathematics.
