hi amit
i assume that you are already doing your project and that is why you submitted your own topic (otherwise you could have very well taken one that we had provided). We are going to review and approve all the self-chosen topics in mid-march. So keep working on your project and wait for the approval from us. Understand that we really cannot take up all the self-chosen topics because it is difficult to find experts in every single field of computer science.
