Well the question is are you not eligible for JOSAA counselling? Or did you not get your seat alloted at the reporting centre? Or is it that you are participating in JOSAA but you did not get a seat alloted even when you are well within the cutoff?

I would like you to check the following

1) Your given category in the JOSAA form

2) See whether you are not gettig confused with home state quota and other state quota

3) All your certificates especially caste certificate

4) Your home state eligibility

5) Whether you filled all the choices properly

And let's hope that your problem gets sorted out.
