Mikayla Munn, 24, was jailed on Tuesday for killing the tiny boy in a dorm bathroom at Manchester University while studying there.
She used a shoelace to cut the umbilical cord, then lied to cops that she had no idea she was pregnant.
Munn claimed she had passed out while giving birth in the tub, then came-to to discover her baby had drowned.
However, police discovered she had texted two men she believed could be the father beforehand to say she was pregnant.
It is reported she also performed pregnancy-related internet searches before killing her baby.
Munn will spend a total of nine years in prison.
