What should I do to learn English for the first time? Can you check my grammar?
would = hypothetical, imaginary situation
should = the best thing to do, what one ought to do
Examples:
“What advice would you give me to learn English?”
“What advice should I follow to learn English?”
“I would read but I cannot find my book”
“I should do my homework if I want to pass the exam”
Hope that helps 😁.
