When I was in high school...I took pre-alg 1 in 9th grade, failed it. Took pre-alg 1 in 10th grade, made a D. Took pre-alg 2 in 11th grade, failed it. Took “Math in the Real World” type class in 12th grade (with a bunch of guys from auto shop) and I think I actually made a C!
So I got to graduate.
I was great at science and lit, journalism, drama...but could not do Math.
But you knw what is weird? Medical math is mostly metric...and I can do it.
I bet you just had teachers who couldn’t adapt to your learning plan.
For instance, we had a set of algebra manipulatives that were basically colored pieces and dice. You could learn to do sets of equations with them without even realizing what you were doing.
If you can do medical math, you can do algebra. I bet if you had a good teacher you’d have done great.
