Which is the difficult engineering aerospace or cse or any other?

Hello Bharath
There is nothing like difficult or easy engineering. Both
Aerospace Engineering and computer science engineering are very good courses. The syllabus and teaching methods are scientifically designed by well renounced professors of different universities. Computer science and engineering provides a good base knowledge on software, development and designing of a software and hardware too. Aerospace engineering provides the knowledge on Aircraft Maintenance, Engine maintenance etc. So Both are very good courses. You have to choose one of these according to your choice.
Thank you.

Hey Bharat!
Engineering is a something so very versatile that it encompasses many fields. Both aerospace and computer science engineering are two of the highly technical fields with good scope in future.
In computer engineering, you study primarily study about programming. If you have a good logical sense and an urge to develop softwares and study about the internal working of the computer, then you will surely enjoy CSE.
On the other hand, if you are fascinated by the working and the development of aircrafts and spacecrafts, then aerospace engineering is the one for you!
Comparing the difficulty of the two fields does not really hold any significance as both require equal amounts of dedication to excel in.
It completely depends on what you would prefer. Because if you choose something that you don't really like, then no matter how much effort you put in it, it will always seem difficult.
Good luck!
