ALL THE BEST FOR APRIL AND ADVANCE!!

Yeshwanth, Although, it is difficult to predict the exact ranks currently as the April  Jee Mains session has yet to take place. However, you can predict your expected rank by this formula:-

(100 - your total score) X 869010 /100.

Also, If the number of candidates for April exam get increased to 1200000 then your final rank shall be (100 - your total score) X 1200000/100

In your case the expected rank comes out to be around 52053 .Note that this is the General or All India rank and not the category rank which is very difficult to predict at this point of time. Also, you havent specified your category and gender status which are very important in determining your chances of admission. So, I am answering your query in a generic way.

Now, at this rank it is very difficult to get admission at any of the good NITs especially the top ones like NIT ANDHRA PRADESH even if you belong to reserved categories. In case you belong to general category, you can get admission to the lower NITs  like the North Eastern NITs, NIT UTTARAKHAND etc.

As regarding your query about Rajiv Gandhi University of Knowledge Technologies, also known as IIIT NUZVID,as per my research, the institute offers 6-year integrated B.Tech program in various specializations and the admission to the same is based on merit obtained in your class 10 marks or the SSC marks and the institute does not undertake admissions based on entrance examinations for the B.TECH course.

However, you have a very good percentile and it would surely fetch you the top branches in some CFTIs and also state level institutions. So, it is advised to appear for state- level counselling too.

Also, you can look at previous years cutoff trends in the following link to understand your chances
