Hello Aspirant,
These Both degrees BA and BSC are three years full time undergraduate degree divided into six semesters.
BA is for humanities or Arts side and BSC is for science side. BA geography deals with human geography which is more theoretical. And BSC in geography has practical aspects.
If you want to go for Civil Service exams I will suggest you to do BA geography as you can choose subject in BA related to you Civil services exams.
Hope this helps:)
