Anand with your 49 marks in the OBC category your rank must be around 55,000. With this rank, I am sorry to say that you won't be able to get NIT Patna even when you have a home state quota. You can check out the last year cut-offs of NIT Patna by going through the link given below:

Even getting admission in any of the lower rank NITs or IIITs is also very slim. You can still check out the following links for knowing the last 2-year cut-off:

Still, you can get admission in the private engineering colleges and the colleges where you have a high probability of getting admission you can check out the following link:

Also with 49 marks in the OBC category, you have cleared the JEE Mains cut-off and you are eligible to sit in the JEE Advanced examination. So, you can apply for it from 2nd MAy to 7th May 2018 and appear in the exam which is going to be conducted on 20th May 2018.

Feel free to ask if you have any more queries. All the best!!
