The University of Nigeria (UNN), Nsukka, has published the admission requirements for its Department of Zoology and Environmental Biology, covering the O’Level subject combination, the JAMB UTME papers and the two cut-off marks that apply.

Two figures matter here and they are not the same. UNN sets a general JAMB cut-off of 200 for every course, while this department sets its own mark at 220.
A candidate scoring 205 therefore qualifies for UNN but not for Zoology and Environmental Biology. That twenty point gap is the detail most worth carrying into your preparation.

Clearing 220 for UNN Zoology and Environmental Biology
The O’Level requirement is five credit passes in English Language, Mathematics, Biology and two other science subjects. Physics, Chemistry and Agricultural Science are the usual choices for those last two.
The JAMB section names Biology plus any two of Physics, Chemistry and Mathematics. Alongside the compulsory English Language paper that every UTME candidate sits, those make up the four subjects the page refers to.
Mathematics is worth planning around. It is a compulsory O’Level credit here, and it can also serve as one of your two optional JAMB papers, which keeps your subject profile consistent across both stages.
On scores, reach 200 to be considered by UNN at all, then 220 to satisfy this department in the screening exercise.
Check your Biology credit before anything else. It is the only subject named in both the O’Level list and the JAMB combination, and no route into the department works without it.
