hello aspirant,

its completely fine if you are preparing for ceed exam. however there is no percentile or age limit for ceed exam. but different institute has different graduation marks criteria for admission in m. design. like iit delhi needs atleast 60% marks in graduation , 55% for sc/st. so  if you are from general category you will not eligible to apply. as per your score you can apply in iit bombay, iit guwahati, iit hyderabad, iit kanpur, but you need to bring a really good score in ceed exam, unless as per your profile there is very little chances of selection.
