Engineering Entrance Exam

It depends on you. If dropping one year makes yourself sure that yes, you can take admission in a good IIT then dropping 1 year is fine but after even investing your one year if you are not getting into IIT or not getting desired job it is truly waste. So, please make yourself sure and confident that Yes, you can get into IITs.
Otherwise, your second option is also not bad. But you get less career opportunities there.
Best of luck.

Hello,
If you score below cutoff marks in JEE Mains, then you cannot appear for JEE advanced.

You should brush your basic concepts for mathematics, physics and chemistry.
All the best.

You need to complete class 12th with physics, chemistry and mathematics to be eligible to enroll for TNEA exam.

Hello,
The cutoffs are declared by CBSE every year along with the declaration of results of JEE Mains.

Hello Subhamoy,
It is interesting to read brochure of IISc. It says, candidates will be selected on the basis of merit list that will be based on any one of the following national level tests. This includes JEE Mains and JEE Advanced.

OBC reservation is almost same as compared to general. So, the rank for general category is the approximate rank for OBC.

KIIT is better than VIT. But, VIT is not a bad college. If you want, you can go for BITSAT too.

Hello Ashish Negi,
The candidates appearing for JEE Main 2017 must have completed class 12th with physics, chemistry and mathematics. However, to get admission in IITs, NITs, IIITs and CFTIs, a candidate must have secured at least 75% in their class 12th board exams (65% for SC/ ST students).
No board marks will be taken into account for calculating JEE Main score from the year 2017 onwards.

No, it depends on how many marks you get. If you get 100 or more, you will get an NIT.
