You've not shared much details about your area of interest so its little tough to guide you. Its always best to select the stream and subjects in which you want to opt for the IAS entrance test and then study them properly to have a 100% command on those subjects. You would be glad to know that UPES Dehradun has come up with special BA program for IAS aspirants.Its BA in Public Policy with IAS coaching embedded. Unlike regular BA this program curriculum is specially focused on IAS preparation and is supplemented with IAS coaching. This can saves lots of time which students generally spend in managing graduation and coaching separately. You can pursue this program if you have interest in this subject. As you have just passed your +2, you have enough time to have command on the entrance examination, so do not wait just start your preparation from today itself.
