Hello aspirant,

In order to get eligible to write UPSE Civil Services Exam (IAS) then you must have passed any Graduation degree course in any discipline from a recognised College or University.

So, if you are interested to do B.Sc Yoga then it's fine and it is a good course too. Directly yoga degree can not help you to become IAS Officer but may help you in achieving the target because in Yoga there are many ways to attain stable concentration, peace of mind, etc which you can use while preparing for UPSE Civil Services Exam (IAS).
