I am 37 years old and I have a mild learning difficulty. I never went to a special school, but yes, I got some help and I never got held back. I left my grades on borderline. I always loved to learn how things function and work in the world and my strongest point was computing and tech.
Now I want to continue my life work. I have always liked maths and physics but never grasped them until now. I love to solve things, and now all I want to do is learn enough maths for physics and engineering and to help me get a good reputation on maths and physics stack exchange sites.
I use Khan academy and I was going going to go from level to level, but I find that boring. I love to learn new things. I have a maths capability of a 4 or 5th grader, and understand maths better now. My interests are electronics. For example, I love to learn robotics and how the parts work, and chemistry and bonds, and particle and quantum physics and particle field physics just like the new age physics.
The thing is I accidentally deleted Khan academy 1 moth ago when I got down to ap calculus level and had to restart because I was stuck. Now I am wondering wethere I should continue from geometry, trigonometry and algebra 1 and 2, or continue from where I left of from before I deleted the old account? I am a bit rusty on but familiar with the old studies. Or should I just start from functions, conic sections, polynomial and quadratics, then the trig pre-calc then back onto ap calculus and onwards?
