Hello Anish,

The main difference between a deemed university and university is that a state university is established by the passing of the required legislation by a state government. It is an educational institute established by the state government and also funded by it.

A deemed university on the other hand is deemed to be a university by the UGC under section 3 of the UGC Act of 1956. The declaration may be made by the central government on recommendation by the UGC.

Hope it helps.

Good Luck!
