There are lots of career options after BA but which will be best for you depends upon :-

• your interest
• what you want to become in your life , for example if you want to be an IAS /IPS you need to go for UPSC examination

For example,

• If you are interested in teaching then after your BA, you can go for B.Ed and after the completion of B.Ed will be eligible to teach in schools
• If you want to study further then you can go for masters in arts etc and later on you can even become a professor
• You can go for LLB and can be a lawyer
• If you want to get into civil services like IAS etc then you can start preparing for UPSC examination after your BA
• If you want to get into management or business or HR jobs etc then you can even do MBA etc.
• If you want to get a job in a bank , you can go for exams like SBI PO etc

I hope my answer helps. All the very best for your future endeavors!
