Which is better for UPSC CSE PREPARATION BA or BA Hons in political science from DU?

BA and BA Honors are both excellent choices for UPSC CSE. It will aid you in your preparation for the Prelims and Main exams.

In BA course, you must study three different subjects, such as political science, history, and geography, which means that 50% of the syllabus has already been covered, and if you choose Political Science as an optional subject, another 40% has already been covered. So taking a BA course will improve your chances. 

Now, moving on to the BA (Hons), you will study political science in depth, which will help you in the Mains because, as we all know, the difficulty level of optional is higher than the Bachelor level but lower than the Master's level, so it will benefit you greatly. However, because you will only be studying two subjects in your bachelor's programme, you will have to study the third subject on your own.

Thus, you should pursue a BA General course. However, as everyone knows, UPSC is all about extreme hard work, luck, proper planning, guidance, and several other factors. Make your own decision and put in your best effort.
