Hello Aspirant,
See the cut-off for which you are talking is of last year i.e. 2019 and the cut-offs are bound to change every year depending upon various factors such as the number of candidates appearing in an examination, the number of candidates qualifying an examination, difficulty level of the paper, and so on. Now as you have scored 500 marks and last year the cut-off for the institute was 409 for AIQ counselling so cut-off will change this year but not with much greater variation and cut-offs are also expected to increase this year so the cut-off might get increased to around 450 or 460 marks so then also you will have good chances to secure the seat in KIMS.
You can check out previous year's cut-offs for other government medical colleges from the link given below :-

Good Luck!!
