Dear Meena,
As of now there is no need to give JEE exam for bsc- animation programme. And you can pursue this field from any stream whether its science , commerce or arts.
and for the admission process you need to contact to particular university or college in which you want to apply for bsc-animation

With this score you can't get any govt institute but in private ones you can get good colleges like Jaypee Institute of Engineering and Technology, Galgotia, UPES Dehradun, UTM Shillong & MNIT Bhopal.

No, NATA is also a national level exam for architecture for top private colleges of architecture. But if you want to do b.arch from NIT's or spa's then you will have to appear in jee main.

Definitely you can easily score that much marks.
That is what all class 12 students do.
As you are preparing for jee mains your boards become obviously easy.
good luck

depend on your 12th result

If you want to do b.arch from IIT's or NIT's then jee main is the only gateway. Or else for other top private colleges of architecture you will have to give NATA. You will easily get information about it on Web as it is popular between b.arch aspirants.

JEE score around 95 and board marks around 60-65%.

There is no chance.
