Hello, I would suggest you to go for some other subject like political science ,economics, sociology, psychology, history, geography etcetera for UPSC as those subjects might help you in your mains and prelims as well, while the language section is only qualifying as you need only 33% in it , so I would suggest you to get into BA Honours of some subject which comprises of UPSC mains subjects or your optional subject. you being a PCM student can also go for BTech as physics,chemistry maths etc. are also available as optional subjects but they might not help you in prelims and mains.
Hope it helps.

Hello Aspirant!

As you want to become IAS, then you must go for BA Literature  as BA comprises many subjects which is similar to syllabus of IAS exams.. Whereas in other courses,  you cannot find any relation with the IAS exams as well as it will become  tough for you to manage BSc along with IAS preparation. However, you can prepare for IAS exam as well as can study BA parallely. 

Hope this helps you :)
