I don't think you need to do all that for them.
lol i flunked high school freshman English (grammar semester) and then got an A in the creative / poetry/research paper semester.
my parents were pissed..
Now i think i had/have some dyslexia and for sure adhd. (ie they wanted to put me on Ritalin in the dark ages ie grade school, but mom told em to pound sand.)
so i had to take more than 4 years of English and still got a 15 on the act when all the others were 30+( up side is i got to take paperback lit and Science fiction so i had a period a day when i got to read.) lol to get an A you needed 2k pages read per 9 weeks i legit had 20k all 4 quarters.
the invention of spell check and word have helped, but i still mess up.
i typed(manual typewriter) a paper in university ( where i spelled one word 7 different ways) still got a A-.
