Sir,I have scored 164 in mains 2015 and 94.6 percent in boards.also,my score in advance is 160.i dont think that i will clear advance with this score.do i have the hope of getting into a good nit?should i take a drop to score more in jee?

I p[ropose to check the cutoff list of the NIT where you aspire to pursue your degree, there is no need to drop a year. you need to visit the elite class institutions of engg, where the placement count as well as pay-package is quite good. try at – 

Birla Inst Of Tech, Mesra

Lovely Professional University, Phagwara

BHU, Varanasi

JJTU, Rajasthan

you can check the cut off list of nit in official website

if you did not cross the cut off then

it is better to drop off
