Hey.

There is a lot of scope for you in various career options and courses that you can pursue after BA in Political Science. You can go for MA in Political Science which is one of the most common options after the UG course. You can go for PHD further if you wish to join the teaching line. You can go for a 3 year Law degree after graduation in Political Science. Other than that various people prepare for Civil Services to become IAS, IPS, IFS officers etc, so you can do that to.

Best of luck
