Hi waseem 

Both UPES and IPU are good colleges.

But in petroleum engineering UPES is better.

Placements in the college are quite good, and it also depends on the quality of students. Last year, the average salary package offered was almost 4-4.50 LPA. The placement rate of college is almost 100%. The college will provide you with opportunities, but you have to make some efforts to take them. Infrastructure is nice and faculty members are experienced, they majorly help students getting placed.

But this college is expensive than IPU.

Now its up to you which college you would prefer.

Hope this information helps. Good luck!
