This graph shows IIT / NIT admissions by education board for the year 2016-17.
It clearly shows that CBSE students outshine the state board students. Telangana, Rajasthan and Andhra Pradesh boards do while Tamil Nadu State Board doesn’t appear in the list. Probably TN board students who got admission were so minuscule that they didn’t figure in the data set.
Time the educators make a note of this. ( based on data from india vidya . com)
