Hello Aspirant .

Since you have not mentioned the exam in which you secured this rank I assume you are talking about NEET UG . When it comes to cutoffs , for government medical colleges through AIQ you need to have a rank below 10-15K but since your rank is almost nearby , you will have some decent options in AIQ. However, with your rank you can definitely  get top government seats in your state counselling.But if you are an outsider in a state counselling then , you will be offered only private college seats. And coming to private colleges , you can get get good private colleges with ranks till 30-40 based on the number of seats available. For many other regular private college it may even go till 1-2 lakhs .A rank of 18000 is very good for many decent colleges but as you have not mentioned the category it is difficult to say exactly because cutoff ranks vary with categories . For instance , for CMC Ludhiyana, if you are a UR candidate , then you will need a rank below 15K or a score above 580 so it will be difficult for you, but if you an OBC or SC candidate then it is 500+ and 380-400 respectively , so your rank would be fine to get in. Anyways you may use the below link to checkout the cutoff ranks category-wise for all the colleges you want and apply accordingly:
