Hello Kanishka, LEET is the generic name for entrance exam conducted for admission in engineering via lateral mode. It's not all India test. Every state has it's own method. Some states admit students based on marks of Diploma also. I would therefore like to advise you that please have a look at the webpage of "dte of tech education" of your state for information and other details. In case of difficulty please do not hesitate to ask further questions. Best wishes to you.

Yes, you will definitely get a admission in bit, you just have to visit there and consult about the procedure. Because I don't know the exact procedure but I can surely say that you can get admission.

You may get admission in all the mentioned institutes but chances for NIT-Trichy and NIT-Surathkal are somewhat higher than DTU.

No, you can't get a seat in DU because of the cut-off which will not be less than 90 percent.
