Hello aspirant,

Well through your JEE Main score you can get seats in colleges like NITs,IIITs and GFTIs. Other than these colleges, you can get seat in those colleges where they accept JEE Main score. Now to get into NITs,IIITs or GFTIs you have to be first JEE Main qualified. Below I have provided 2019 JEE Main cutoff (percentile) category wise - 

• CRL : 89.75
• GEN-EWS : 78.21
• OBC-NCL : 74.31
• SC : 54.01
• ST : 44.33
• PwD : 0.11

Now if you have cleared the cutoff as per your category then you are eligible to get a seat in NITs,IIITs and GFTIs. Now you will get these seat through JoSAA counselling. For other colleges than these , you have to attend the counselling for those respective institutions since they don't participate in JoSAA. You can go through thus link and checkout the details regarding JoSAA cousnelling : https://engineering.careers360.com/articles/josaa-counselling 

And, if you didn't get a seat through JoSAA but is JEE Main qualified then you can apply for CSAB counselling which will begin after completion of JoSAA counselling and is conducted for admission into NITs,IIITs,SFTIs,GFTIs. You can visit this link and check the detailed information about CSAB counselling : https://engineering.careers360.com/articles/csab

Hope that you get a good college. Good Luck !!!
