NIT

You can try your luck in DTU counselling. IIITs and NITs seem to be tough with this rank but anything is possible. You just need to have patience and wait for all the counselling till spot round. GFTIs are not as much better option as the above two are, so keep that as a back up plan. All the best.

GFTI is possible. You can also apply to your state level entrance counselling with your JEE Mains rank. NIT is also possible if you have enough patience to wait till the spot round counselling of JEE.

As per recent news, there were no announcement regarding one course for engineering.
So, the chances for MHCET to be happen in 2019 is more.
Wait for the further announcements.

Yes of course, you can join preparatory course in IIT if you qualified under preparatory course in JEE Advanced in your very first attempt.
Generally, the cut-off for preparatory course is less than general cut-off.
Thanks.

Hello Akash,

However, as per your rank, you may not get allocated any seat in the first round but as the counseling process, you will get good branches at lower NITs.

Hello Dear,
Here is a tool called college comparison app by Shiksha. You can compare any two colleges. Here is the link:

Only if you do good in mains as well as scored minimum 75% for general and 65% under ST/SC category.
So, you need to work hard for another year.
And you have to appear in Mains and scored a good rank accordingly.

Hello Avinash,
There is no chance to get any NIT or IIIT because you have not score 65% in 12th board, but you can try in a private college. I think you can get a good private engineering college.
All the best.

For your category, JEE Mains rank for CSE branch is under 20k in NITs and DTU but in IITs, you should score under 2000 rank for CSE.

Hi Vaibhav,
A minimum of 50% is recommended however class 12th scores carry less weightage, your admission will be based on the NATA scores mainly.
