I think its a good combo. But i am not knowledgable on what degrees you can do woth this, this would be useful to research and see whatt type of field/. Job you want to go into in the future and then do more research on it.
As long as you feel comfortable with your choices it is good. If you like sociology thwn go for sociology but if like english lit them do that. Dont change a subject just cause of essay based reasons unless you really like to do essays and would prefer english lit because of essays . Maybe check with your teachers or reasearch cause i think sociology also has essays. Also if you want to go into international relations then research. To see if your subjects match with uni degrees.
