I have heard that there's no sectional cutoff for the NITIE which was announced. I have 97 percentile but my VA is lower than 80. Should I expect a call from NITIE?

Usually, the college does not reveal the sectional cutoff on an official basis. On average, the cutoff are decided depending on the applicant pool and this could also decrease after a while by a few percentiles. This is true for a few sections but expects it not to go below 80.

With your current scores and past trends, if you are from the general category then you will not get a call back from the institute.

If you are lucky with respect to your applicant pool, you might have some small chances, but my advice to you would be to look for other options and not keep high hopes.
