Architecture

Both the fields are totally different. It depends on your interest. If you are interested in planning and designing then you can go for architecture if not prefer engineering.

The course fees is INR 68,400.
Thanks

It is difficult to predict the marks as for now results only percentile score is released. If you want you can calculate the percentile rank. But no formula is there to predict the marks. Use this formula to predict the rank:
Rank Formula = (100 - your total score) X 145386 /100. Your rank may differ

If you are general candidate, then no. Work harder, try to get at least 98.5 percentile to stand a decent chance to get into one of the NITs, IIEST or B.Plan in SPAs and MANIT.
You can try for different private and semi-private colleges. There are plenty of Architecture colleges apart from NITs and S

You have to wait for the JEE results, which will be released on the month of April by national testing agency NTA officially. The cut-off will be announced in April for JEE advance, so you have to wait till April to know the cutoff for JEE Advance, because it will depend upon the number of students

It does not fully depend on class 12th percentage, but you have to have minimum eligible percentage to get the admission.

Your percentile is very good. There is a chance to get JJ College of Architecture, Mumbai. You can try for this company.

Yes you will get it.

Yes,you will get B.Arch very easily. Just participate in counselling process.

No, you don't have any chance to get in NIT's, because your percentage is very less. If you are interested in only NIT's, then you can appear for the exam again.
