Hello,

To get a seat in Nit you have to score a min of 160 marks for a good college, But if you want to get into the top 5 nits scoring 190 above is just so as to get good branch too. Jeemains is not that tough and if you focus more on the basics part you can easily score above 180. Concentrate more on ncert textbooks and practising previous papers.

Hope this helps...
