AOC - COLLEGE YEARS VS CALENDAR TAX YEARS

Hi,

My stepdaughter lives with us and this is her scenario:

w-2  $34351.00  ,   1098-t    (box1 $8969   box 5 $4344)

dob 04/24/1996 ( as of 01-01-2021  =24 years and few months)

as of 01/01/2020 did not complete 4 years of college Graduated may 20 2021

( IT t took her five years to finish school) never claimed AOC BEFORE

one semester in 2021 Jan - May 16 full time student

Obviously we can not claim her but her concern is taking longer than 4 years to graduate( 3rd year took her longer than it should)

Is  the number of years  an issue because it took her a little longer to complete  education.  will this   disqualify HER  from AOC ?
