Hello,

Eligibility criteria for UPSC is Bachelor's Degree in any discipline from a recognized university, in addition to have attained 21 years age.

UPSC syllabus is more inclined towards humanities subject, that's evident from Prelims and Mains syllabus, even through science is a part of it but in a limited way.

To answer your question, it depends on a lot of thing, first are you a science student and want to continue with this stream, if yes please go ahead, you can manage UPSC syllabus, also you can select science subjects as optionals, people from engineering background too have cracked UPSC with science optionals.This stream opens avenues in different sectors as well such as corporate ones.

However, if you're more inclined towards humanities subject and feel having studied this will help you in UPSC preparation, it definitely will be an added advantage to you. Because you'll be more familiar with arts subject which is essence of UPSC syllabus. Choose this only if you have only one aim in life that is to crack UPSC. In this sense, you'll be more clear and focused about your goal since starting.

Hey there

If you are asking whether simple graduation is good for upsc civil services or engineering then it's true that nowadays engineers are going for civil services and are getting top ranks. But honestly engineering does not help for upsc civil services engineering teaches you technical knowledge and civil services wants administrative skills. If you want to do civil services then you can choose arts which will help you in upsc like history honours etc.
