Hey there!

The cutoff marks of BHU Zoology depends on seats and number of students applied. The marks varies every year which again depends on certain conditions.

As you must know that BHU has reserved seats (Aprox 25%) for UG students who has studied B.Sc. from there. So the marks for post graduation varies.

As for obc 2018 cutiff goes for 60 but this year the paper was of more weightage so the cutoff would be also high.

So yes there are very very less chances that you might get your seat reserved.

Don't lose hope try something else.

Best of luck!
