20000 rank which college going to get ?
Dear aspirant
You must mention the name of the entrance exam , name of the counselling process , name of the institute(s) where you want to get admission , your category so that we can suggest you with precise informations and clear your doubts.
However I am telling you on a general basis.
With 20000 All India rank you can get various NITs , IITs , GFTIs by JEE MAIN and with 20000 All India rank you can get government medical colleges by All India counselling.
You can check your chances here
Next time be specific and we will be able to help you.
Best Wishes.
