JEE

Gaurav, in absence of JEE you can try for admission in private universities like Amity, Lovely, Manipal, etc which have their own admission tests for B.Tech.All these universities have wonderful infrastructure and world-class facilities to offer to students apart from good placements that they offer. Some of them even offer scholarships.
Good luck.

Hello Abhijeet,
The IITs and NITs do not provide lateral entry admissions. So, that you cannot get admission the second year by direct admission.
If you clear JEE main also, you will be eligible for the 4 years B.Tech only. You need to discontinue the institute and join an NIT.

As you have mentioned that you want to become data scientist, I think IT is for you.
For further information, you can check the link below where there's comparison between CS and IT:

I hope it will help.
All the best.

Hello Ankush,
Most of the people prefer to prepare itself only so don't get dishearten and work hard, and regarding books, you can choose Cengage and Arihant Publications books for both physics and maths and for chemistry books like NCERT, Top Tandon, Ranjit Shahi, etc.

Yes, surely, a successful drop can change year life but for this, you need to do lot of hard work.
For the complete 1 year, you have to sacrifice with each and every thing and should concentrate only on your studies. So, if you are ready to sacrifice and study well. You can take a drop.
Hope this helps.
All the very best.

A bit tough, but don't lose hope. Seeing last year's spot round cut-off for the general category which was 200, you still have a chance.

You didn't loss anything right now. There are so many NIT in which you can get admission.

Hello Madhur,
Yes, you can definitely clear JEE main examination with a good score by self-preparation. If you have regular practice in solving problems then you can easily score 150+. You need to have concept clarity with a great speed and accuracy in solving problems and practice many mock test papers.
But to clear JEE Advanced, you need a guidance in the most efficient manner.
So try to have coaching for JEE Advanced but you can clear JEE main without coaching.

No, you have to score more than 75% if you are from CBSE. and if you are from CBSE then you can give the exam as at the time of exam they only ask your % but you have paid the fee for then you can appear for exam but you cannot get admission in college by JEE Mains.

It depends on your JEE mains score. To get admission in this college, you need to score around 250 marks in JEE Mains.
Good luck.
