Hey aspirant!

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

In your case the rank comes out to be around 43971.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, the EWS Category is a relatively new category and so, predicting its cutoff is very tough. However, you can look at previous years cutoff trends in the following link to understand your chances

Now at this rank it is very difficult to get CSE at any of the NITs especially the good ones like NIT ANDHRA PRADESH even if you belong to General EWS Category. The CSE for most of the good NITs close around 10000-12000 rank and after that you can get the lower NITs only like the North Eastern NITs. 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 have another attempt to go in the April session, so concentrate on it and work hard to improve your scores and chances of getting your desired college

Also, you can use this college predictor to know what colleges you would get based on these January scores
