i have a general Q !! does internal rhyme affect the rhyme scheme? the answer is very important 4 me! thanks

No, the internal rhyme of a line is very important, but it
does not affect the rhyme scheme.  Rhyme scheme is just a way of representing the
pattern of end rhyme in a poem through the use of letters.  For
example:

Mary had a little lamb
(A)

Whose fleece was white as snow
(B)

Everywhere that Mary went
(C)

The lamb was sure to go
(B)

Because "snow" and "go" rhyme, they are assigned the
same letter.  If a poem like this had some internal rhyme (rhyme within the line), then
it would change the sound play of the poem, but the end rhyme would remain the
same.
