JEE Scores

If you belong to reserved Kotak, then you only need to show is your category wised ranking. Many colleges seek admission on the basis of all India ranking but the traditional way is according to your category wise ranking.
Best of luck for your future!

Depends on your rank. If your rank comes around 1000-1500 in general PWD, you may stand a chance. Chances are less for old NITs but you may get a seat in the new ones.

You can get admission if you have a very good score in MHCET.

Sorry, but don't think you will get a government college, but you can try some other university examination.

You should be between 3k to 5k to get admission in IHM-Mumbai in 1st round. And for 2nd round, you must be between 5k to 7k. I suggest you to not join IHM-Mumbai or any other hotel management course, better do simple B.Sc.
I am writing this because, I got IHM Mumbai in 2017 in 1st round of counselling, but after reporting IHM Mumbai, my mindset changed by seeing the scenario of the hotel industry and withdrew my documents and seats on the second day after that.
Currently, I am preparing for Engineering competitive exams.

Yes, you can get admission in that college but you can face some problem if you don't have home state quota.

For admission in any college, JEE Mains marks are considered of that year in which you are applying for admission. There is no importance of previous year's marks of JEE Mains and Advanced in the admission process. Thank you.

Hello Ashwin,
