JEE

Thapar University is one of the deemed universities you can opt for.

Yes, that would be better.

It is a previous pattern in UPSEE that you may see in the previous year question papers but this year, pattern is 50 questions each from PCM that is total 150 questions and each correct answer carries 4 marks and there will be no negative marking.
You have to score less than 30k rank to get admission in this college.
All the best.

Graphic Era, DIT, Uttaranchal Institute Of Technology, College of Engineering, Roorkee are some good colleges according to your rank and marks.

Go for state board. It will give you much time to prepare.

Hello Mahendra,
What you are confessing is quite serious. If you are not able to score minimum 75% marks in 12th then preparing for JEE Mains would be futile. I suggest you take some dedicated tuition from your teachers and see how your ability develops.
Best wishes

Hello Saptarshi,
It's a decision to be taken with analysis. There are plenty of students who take drop & prepare exclusively for JEE Mains & Advanced. Caution needs to be exercised that perseverance and dedication for study needs to be maintained. If you can then go ahead with your plan.

How much marks you are expecting in this year? I may tell you whether it will be good to drop one year only after that.

If you are sure that you will be getting 110 marks then you should wait till the commencement of JEE Advanced. Prepare for Advanced, a crash course might help you for the same. All India ranks will be announced in the month of June on the basis of which admission will be given to top NITs and state government colleges. All the best.

Go through other engineering entrance exams such as WBJEE, UPSEE, BITSAT, COMEDK, CUSAT and others.
