Hello dear..I can understand your confusion it's quite common at this stage but no one else will decided for you , you yourself have to decide. Geography and Psychology are different poles. You have to choose one ( if want to pursue Hons.)according to your interest and aim. If you are interested in  reading human and animal behaviour psychology is your stream but if you are more inclined towards study of place, environment, Ecosystems, weather process, climate change etc then you should opt for geography.

Both the subjects are good for civil Services. But it's on you, how you make it, and it's only possible when you choose something what you are interested in reading.

You can also choose for Regular / Programme B.A where you have to choose 3 subjects for your B.A course. Through this course you will get time to explore your interest and will also develop your understanding about you interest and capabilities.

Hope it helps.

Good luck
