CBSE 12th

Hi Sheetal,
Choose a course you are interested in. Still if you want a course to help you with the preparation of IAS, you can choose BA in sociology, history, economics or law.

No, you cannot. Try for privates.

No, you wont be getting any of it bcz your JEE marks are way too below the cutoff.

If you belong to SC-ST, then you'll surely get a NIT. If you belong to OBC, then also you have a good chance of getting into a NIT. But if you're a General, you wont get. And no one gets into IIT just by giving JEE Mains. To get into a IIT, you have to score well in JEE Advance.

If you want you can do BA(major) psychology at Tata institute of Social Sciences or Sam Higginbotham institute of agriculture technology and sciences(UP)Allahabad

first of all you are not clear jee mains,So there is no chance

You can check your predicted rank on resonance rank predicter or shiksha jee main rank predicter

What is your board % ? I think you can get any NIT.

For admission into XLRI , you need passing grades in all these standards you have mentioned. There is no minimum cutoff mentioned as such but a higher spectrum is generally favorable or required. I would say that more than 90% of students who have got admission into XLRI would have more than 55% in 10th and 12th
