For getting in IPU there are 2 criteria and those criteria depends upon if you are a resident of Delhi.

1. By JEE MAINS - Through JEE Mains you can get any good college. If you are having Delhi residence certificate then you need to score 50 to 60 marks only in JEE mains. This is because Delhi residents get 85% relaxation in admission.But if you are from other state you are supposed tp score 100+ score.

2. Another way to get into IPU is clearing the exam which is conducted by IPU every year . In this also the state category certificate works. 85% seats are reserved for Delhi residents.

I hope you find it relevant!
