I got 28.38 percentile in cat .10th- 89%, 12th- 85%, UG- 62%. will I get a seat there? And what type of questions will be asked in WAT & PI?

Your cat percentile is very low when compared to last year, so have very less chance of getting selected. Last year we had written test and PI. In PI, its generally talk about yourself, why MBA?, why VIT? . Like that. Written test we had essay writing.
