Does admission to iiit-hyderabad depend on jee main marks solely or jee main rank ?website lists it as marks.

JEE Main rank..and it is predicted on the basis of 60% JEE Main marks + 40% class 12 qualifying exam marks..
IIIT H is a good Engg College, so try to focus on JEE Main exam to get a good rank..
Good Luck..................................................................................................................................................................................................if
