Request grammar input

Hi I’m struggling in my bunpro reviews with a group of grammar. The questions ask will you, would you, wont you, for me etc. but all use different grammar points which are very similar but the prompts seem to be the same

てくれる andてもらう the prompts dont seem to change an the only indication i have for either is when ni is after the listener or speaker, but sometimes that’s not clear

てくれますか andてくれない
てもらえませんか
てくれませんか

Would you supply some screenshots? With that, we could give pointers on how to differentiate. If I understanding correctly, I have the opposite issue. The grammar prompts allow me to answer without reading the questions.
