SSD, you are describing a badly designed and poorly used checklist. There is such a thing as a good short to the point checklist, used intelligently.
I'm the first to express my strong views about these daft massively overlong checklists used in some schools, but because bad practices exist, does not mean that good practices don't exist.
And from his age and question, I still think that the best advice we can give the OP, is to do what his instructor tells him, given that presumably he has strong ambitions to pass his skill test, before he starts copying the bad habits of cynical and over-opinionated PPLs !
