a little confused

so im doing the courses but on the warm up part it doesnt say anything about what notes im doing or what i should be doing of figuring out how to tell if im doing it properly so i feel like im just following along blindly not sure im im hitting pitch what pitches i should be doing i honestly dont know anything about matching pitch or staying on pitch or anything so if i do the exercises but am not doing them right or understand why im doing them it just makes me feel lost is there like a super begginers course or something to help understand this stuff cause like the ooo walk down i understand the convept but what notes should i be using and how do i know if im hitting them right if i just doo the ooo and go down but am not doing it right then is it even helping me or
