JEE Main

Dear saikant
as you are well aware that NITS take admission based upon the cut of decided by the JEE.so it will be decided at the time of counselling whether you will get the seat.even if you didnt get any NIT dont dishearten yourself, there are some private instituion like ,BITS, Amity,VIT ,LPU,SRM etc which provide good education along with good placements.
best of luck

There are many colleges that take separate exams like Bits, Manipal, VIT Vellore, srm, IPU etc. You can also take your state exam like there is UPSEE for UP.

It depends on each years paper pattern. But 130 is a safe aim.

HelloIt will depend on your 12th passed year.But i am sure , you are not eligible for jee advance. If you passed 12th exam in 2015 than you are eligible for jee main 2017, otherwise you are not eligible for this exam.
thanks
best of luck

290+ from next year.
