hello aspirant,

if you are preparing for NEET 2020 then i will suggest you do not go for any expected marks just work hard that much as much you can do .Because the college cutoff depends on no. of candidates seating in the examination and many other factors . But if you are willing to know   then you have to score minimum 560+ to get admission in government  college  easily.

To know more cutoff go through following link-->

Good luck!
