If you have scored 215 out of 400 in IPU CET, your position would be somewhere close to 10000-15000.

So assuming you need a great school in IPU you need to score at least 300 marks on your test then you can get effectively the top 3 schools in IPU like Maharaja again, MSIT and VIPS. You want to get a position under 4000.

I trust this will help you and best of luck!
