JEE

Okay, I got your problem. This is the same thing happened to me during my JEE preparation time. Now, when you try to solve the given problem on maths do write all the given values first in a copy then write what is to be find. 50% work is done here. Now, you got the way - What to find? Now Think is there any formula or any type of method used in the mathematics book then do it. I am 100% sure this will help.

No, it is not necessary to give exam of JEE to learn B.Tech, you can go for other university exams too.

Hi Akansha,
Yes, you can definitely apply for BITSAT in the next year as BITS Pilani gives two chances for getting admission. So, prepare hard and get into this beautiful place.
Best Wishes.

Hi Ritesh,
BITS Pilani only accepts BITSAT score for admission into their engineering courses. However, for Amravati Government College you need to appear for MAH-CET exam. These institutes don't accept JEE Mains score as their admission criteria.
Best Wishes.

Under 1500 should be good enough. Again, this is just a rough approximation. The cut-offs vary every year.

You can definitely get admission in B.Tech with state level exam. It is not necessary to give JEE for B.Tech. Best of luck for your future and if there's any query, feel free to ask.

As per these year's cut-off, the minimum marks required to lock an NIT seat is 128-140 marks. Its completely depends in the branch and NIT-college.
All the best.
