IIEST have abundant things to say. The professors are cooperative and helpful. Designing is taught through MMS lab and CAD lab. In 3rd year, students go to IITK for flight laboratory. Many of the student do internships at HAL, DRDO, etc.

On the second hand PEC is also definitely better college for aerospace engineering. It had Kalpana Chawla as it's student. PEC is itself a reputed institution of the Punjab Government.

Choose wisely.

Good luck!
