Hello Aspirant,
Since you have not mentioned your category so considering it as general.
As we go through previous year's (2019) cut-off then it shows that in 2019 the cut-off marks was 601 for Guwahati Medical College, Guwahati under All India quota for General category and we saw an increase of around 25-30 marks in institutional cut-offs in 2020. So if you are targeting for NEET 2021 then your aim should not be less than 640 out of 720 marks.
You can check out previous year's cut-offs from the link given below :-
